Now, Chalmers researchers have begun work on developing a quantum computer with far greater computational power than today&#39;s best supercomputers.​</b></p><div><span style="background-color:initial">The days are currently full of interviews. Per Delsing, Professor of quantum device physics at Chalmers, is busy recruiting high-level researchers and doctoral students to help pull through a very challenging project: building a quantum computer that far exceeds today's best computers.</span><br /></div> <div><br /></div> <div>&quot;To get the right staff is the alpha and omega of it all. But it looks promising, we have received many good applications&quot;, says Per Delsing.</div> <div><br /></div> <div>The development of the quantum computer is the main project in the ten-year research program Wallenberg Centre for Quantum Technology, launched at the turn of the year, thanks to a donation of SEK 600 million from the Knut and Alice Wallenberg Foundation. With additional funds from Chalmers, industry and other universities, the total budget is landing nearly SEK 1 billion.</div> <div><br /></div> <div>The goal is to make Sweden a leading player in quantum technology. Indeed, recent research in quantum technology has placed the world on the verge of a new technology revolution – the second quantum revolution.</div> <div><br /></div> <div><a href=""><img src="/SiteCollectionImages/Centrum/WACQT/Grafik%20kvantteknolgi_liten.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:300px;height:178px" />​</a>The first quantum revolution took place in the 20th century, when one learned to utilize quantum mechanical properties of light and material. This led, among other things, to the laser and transistor – inventions that underpin information technology that largely shape today's society.</div> <div><br /></div> <div>Now scientists have also learned to control individual quantum systems as individual atoms, electrons and photons, which opens up new opportunities. In sight, there are extremely fast quantum computers, interception-proof communication and hyper-sensitive measurement methods.</div> <div><br /></div> <div>Interest is big worldwide. Decision makers and business leaders begin to realize that quantum technology has the potential to greatly change our society, for instance through improved artificial intelligence, secure encryption and more effective design of drugs and materials. Several countries are investing heavily and the EU is launching a scientific flagship in the area next year.</div> <div><br /></div> <div>&quot;If Sweden will continue to be a top level nation, we must be at the forefront here&quot;, says Peter Wallenberg Jr.</div> <div><br /></div> <div>Several universities and major computer companies, like Google and IBM, are aiming to try to build a quantum computer. The smallest building block of the quantum computer – the quantum bit – is based on completely different principles than today's computers (see graphic). This means that you can handle huge amounts of information with relatively few quantum bits. To surpass the computational power of today's supercomputers, it's enough with 50-60 quantum bits. The Chalmers researchers aim at reaching at least one hundred quantum bits within ten years.</div> <div><br /></div> <div>&quot;Such a quantum computer could, for example, be used to solve optimization problems, advanced machine learning and heavy calculations of molecule properties,&quot; says Per Delsing, who heads the research program.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/WACQT/Kvantdator_180518_11_340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />The Chalmers researchers have chosen to base their quantum computer on superconducting circuits. They have worked with single superconducting quantum bits for almost 20 years and delivered many contributions to knowledge building within the field. Now they are going to scale up and get many quantum bits to work together.</div> <div><br /></div> <div>At the lab, they are currently working to improve the lifetime of single quantum bits. Quantum physiological conditions are extremely sensitive, and collapse if they are exposed to disturbances. Among other things, the researchers paint the inside of the experimental chamber black, so that disturbing microwaves that succeed in slipping through cables are quickly absorbed. They are also investigating and evaluating different strategies for linking quantum bits to each other, which is necessary to be able to perform proper calculations.</div> <div><br /></div> <div>&quot;In addition to the lifetime and the relationship between quantum bits, the number of quantum bits is an important piece of puzzle to solve. Making many of them is easy, but we need to find smart ways to utilize the equipment to control each of them. Otherwise, it will be very expensive,&quot; explains Per Delsing.</div> <div><br /></div> <div>In order for the project to get initiated councils, they are in the process of setting up a scientific board. Per Delsing is currently waiting for answers from eight quantum experts who were asked to be board members.</div> <div><br /></div> <div>&quot;They become a sounding board that we can discuss complex issues with, for instance how fast we will be able to scale the number of quantum bits. The technology we need to build the quantum computer is constantly evolving, and it's difficult to determine when it's time to buy it,&quot; he says.</div> <div><br /></div> <div>On the theory side, the recruitment of competent staff is at the focus right now. Theoretical physicist Giulia Ferrini, expert on quantitative calculations in continuous variables, was in place already in January and the recruitment process is ongoing with a number of applicants. A total of 15 people will be employed at Chalmers.</div> <div><br /></div> <div>&quot;We have received great response and good applicants. Getting the right people is the most important thing – the project does not get any better than the employees,&quot; says Göran Johansson, professor of applied quantum physics and one of the main researchers in the quantum computer project.</div> <div><br /></div> <div>The theoretical efforts will initially focus on developing a computer model of the quantum computer experiment so that they can help experimentalists forward through simulations.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/WACQT/Kvantdator_180518_16.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:350px;height:234px" />&quot;A challenge is to identify early properties which are important in the model, so we do not include too many details when scaling up. Otherwise, we'll hit the ceiling for what a supercomputer can simulate before we reach up to 40 quantum bits,&quot; says Göran Johansson.</div> <div><br /></div> <div>Another important task for the theorists is to explore what a smaller quantum computer model can do. With eight-digit well-functioning quantum bits, one could drive the so-called Shors algorithm – which aroused the world's interest in building quantum computers - and crack today's encryption system. But the first quantum computers, which can do anything beyond what a regular computer can, will be significantly smaller.</div> <div><br /></div> <div>&quot;The question is what becomes the breakthrough application for a small quantum computer. We need to find out what a hundred bit quantum computer can solve for problems that someone is interested in knowing the answer to,&quot; says Göran Johansson.</div> <div><br /></div> <div>Here, collaboration with companies comes into the picture - from them, researchers can get tips for real-life and urgent applications to investigate. The Chalmers researchers have conducted discussions with Astrazeneca, who would have a lot to gain if they could calculate the characteristics of large molecules in their drug development, and Jeppesen who works to optimize aircraft crews and routes. The interest in becoming part of the quantum technology initiative is generally large among companies that have challenges that would be appropriate to solve with a quantum computer.</div> <div><br /></div> <div>&quot;They are keen to not miss the train. This can go quite quickly when it's getting started, and then it's important to have skills and be able to get up at the right pace,&quot; says Per Delsing.</div> <div><br /></div> <div>Text: Ingela Roos</div> <div>Photo: Johan Bodell</div> <div>Graphics: Yen Strandqvist</div> <div><br /></div> <div><a href="">This is a text from Chalmers magasin #1 2018​</a></div> <div><br /></div> <h5 class="chalmersElement-H5">Facts about the Wallenberg Center for Quantum Technology</h5> <div>• Wallenberg Center for Quantum Technology is a ten-year initiative aimed at bringing Swedish research and industry to the front of the second quantum revolution.</div> <div>• The research program will develop and secure Swedish competence in all areas of quantum technology.</div> <div>• The research program includes a focus project aimed at developing a quantum computer, as well as an excellence program covering the four sub-areas.</div> <div>• The Wallenberg Center for Quantum Technology is led by and largely located at Chalmers.

The graphene film shows great potential as a novel heat spreading material for form-factor driven electronics and other high power-driven systems.</b></p><div><span style="background-color:initial">Until now, scientists in the graphene research community have assumed that graphene assembled film cannot have higher thermal conductivity than graphite film. Single layer graphene has a thermal conductivity between 3500 and 5000 W/mK. If you put two graphene layers together, then it theoretically becomes graphite, as graphene is only one layer of graphite.</span><br /></div> <div><br /></div> <div>Today, graphite films, which are practically useful for heat dissipation and spreading in mobile phones and other power devices, have a thermal conductivity of up to 1950 W/mK. Therefore, the graphene-assembled film should not have higher thermal conductivity than this. </div> <div><br /></div> <div>Research scientists at Chalmers University of Technology have recently changed this situation. They discovered that the thermal conductivity of graphene assembled film can reach up to 3200 W/mK, which is over 60 percent higher than the best graphite films.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/jliu_2016_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Professor Johan Liu (to the right) and his research team have done this through careful control of both grain size and the stacking orders of graphene layers. The high thermal conductivity is a result of large grain size, high flatness, and weak interlayer binding energy of the graphene layers. With these important features, phonons, whose movement and vibration determine the thermal performance, can move faster in the graphene layers rather than interact between the layers, thereby leading to higher thermal conductivity. </div> <div>“This is indeed a great scientific break-through, and it can have a large impact on the transformation of the existing graphite film manufacturing industry”, says Johan Liu.</div> <div><br /></div> <div>Furthermore, the researchers discovered that the graphene film has almost three times higher mechanical tensile strength than graphite film, reaching 70 MPa.  </div> <div>“With the advantages of ultra-high thermal conductivity, and thin, flexible, and robust structures, the developed graphene film shows great potential as a novel heat spreading material for thermal management of form-factor driven electronics and other high power-driven systems”, says Johan Liu.</div> <div><br /></div> <div>As a consequence of never-ending miniaturization and integration, the performance and reliability of modern electronic devices and many other high-power systems are greatly threatened by severe thermal dissipation issues.</div> <div>“To address the problem, heat spreading materials must get better properties when it comes to thermal conductivity, thickness, flexibility and robustness, to match the complex and highly integrated nature of power systems”, says Johan Liu. “Commercially available thermal conductivity materials, like copper, aluminum, and artificial graphite film, will no longer meet and satisfy these demands.”</div> <div><br /></div> <div>The IP of the high-quality manufacturing process for the graphene film belongs to SHT Smart High Tech AB, a spin-off company from Chalmers, which is going to focus on the commercialization of the technology.</div> <div><br /></div> <h5 class="chalmersElement-H5">More about the research</h5> <div>The work has been done in collaboration with research teams at Uppsala University and SHT Smart High Tech AB in Sweden, Shanghai and Tongji University in China and University of Colorado Boulder in USA.</div> <div><br /></div> <div><strong>The paper is published online in the well-known scientific journal Small, with the weblink: </strong><a href=""></a></div> <div> </div> <div><strong>Related publications:</strong> </div> <div>Nat.

These conditions enable the formation of the graphene film with large grain size, good atomic alignment, thin-film structure, and low interlayer binding energy. All these features have great benefit for the transfer of both high-frequency diffusive phonons and low-frequency ballistic phonons, and thereby lead to the improvement of in-plane thermal conductivity of the graphene film.

This is the findings of new research from Chalmers University of Technology, Sweden, recently published in the scientific journal Advanced Materials Interfaces.</b></p><p>​Operations for surgical implants, such as hip and knee replacements or dental implants, have increased in recent years. However, in such procedures, there is always a risk of bacterial infection. In the worst case scenario, this can cause the implant to not attach to the skeleton, meaning it must be removed.<br /><br />Bacteria travel around in fluids, such as blood, looking for a surface to cling on to. Once in place, they start to grow and propagate, forming a protective layer, known as a biofilm.<br /><br />A research team at Chalmers has now shown that a layer of vertical graphene flakes forms a protective surface that makes it impossible for bacteria to attach. Instead, bacteria are sliced apart by the sharp graphene flakes and killed. Coating implants with a layer of graphene flakes can therefore help protect the patient against infection, eliminate the need for antibiotic treatment, and reduce the risk of implant rejection. The osseointegration – the process by which the bone structure grow to attach the implant – is not disturbed. In fact, the graphene has been shown to benefit the bone cells.<br /><br />Chalmers is a leader in the area of graphene research, but the biological applications did not begin to materialise until a few years ago. The researchers saw conflicting results in earlier studies. Some showed that graphene damaged the bacteria, others that they were not affected.<br /><br />“We discovered that the key parameter is to orient the graphene vertically. If it is horizontal, the bacteria are not harmed,” says Ivan Mijakovic, Professor at the Department of Biology and Biological Engineering.<br /><br />The sharp flakes do not damage human cells. The reason is simple: one bacterium is one micrometer – one thousandth of a millimeter – in diameter, while a human cell is 25 micrometers. So, what constitutes a deadly knife attack for a bacterium, is therefore only a tiny scratch for a human cell.<br /><br />&quot;Graphene has high potential for health applications. But more research is needed before we can claim it is entirely safe. Among other things, we know that graphene does not degrade easily,” says Jie Sun, Associate Professor at the Department of Micro Technology and Nanoscience.<br /><br />Good bacteria are also killed by the graphene. But that’s not a problem, as the effect is localised and the balance of microflora in the body remains undisturbed.<br /><br />&quot;We want to prevent bacteria from creating an infection. Otherwise, you may need antibiotics, which could disrupt the balance of normal bacteria and also enhance the risk of antimicrobial resistance by pathogens,” says Santosh Pandit, postdoc at Biology and Biological Engineering.<br /><br />Vertical flakes of graphene are not a new invention, having existed for a few years. But the Chalmers research teams are the first to use the vertical graphene in this way. The next step for the research team will be to test the graphene flakes further, by coating implant surfaces and studying the effect on animal cells.<br /><br />Chalmers cooperated with <a href="">Wellspect Healthcare</a>, a company which makes catheters and other medical instruments, in this research. They will now continue with a second study. <br /><br />The projects are a part of the national strategic innovation programme SIO Grafen, supported by the Swedish government agencies Vinnova (Sweden’s innovation agency), the Swedish Energy Agency and the Swedish Research Council Formas. The research results are published in Advanced Materials Interfaces: &quot;<a href="">Vertically Aligned Graphene Coating is Bactericidal and Prevents the Formation of Bacterial Biofilms</a>&quot;<br /><br /><strong>The making of vertical graphene</strong><br />Graphene is made of carbon atoms. It is only a single atomic layer thick, and therefore the world's thinnest material. Graphene is made in flakes or films. It is 200 times stronger than steel and has very good conductivity thanks to its rapid electron mobility. Graphene is also extremely sensitive to molecules, which allows it to be used in sensors.<br /><br />Graphene can be made by CVD, or Chemical Vapor Deposition. The method is used to create a thin surface coating on a sample. The sample is placed in a vacuum chamber and heated to a high temperature at the same time as three gases – usually hydrogen, methane and argon – are released into the chamber. The high heat causes gas molecules to react with each other, and a thin layer of carbon atoms is created.<br />To produce vertical graphene forms, a process known as Plasma-Enhanced Chemical Vapor Deposition, or PECVD, is used. Then, an electric field – a plasma – is applied over the sample, which causes the gas to be ionized near the surface. With the plasma, the layer of carbon grows vertically from the surface, instead of horizontally as with CVD.<br /></p> <div class="ms-rtestate-read ms-rte-wpbox"><div class="ms-rtestate-notify ms-rtestate-read 21aa3563-502e-4205-bcb8-3e04875a5b8d" id="div_21aa3563-502e-4205-bcb8-3e04875a5b8d" unselectable="on"></div> <div id="vid_21aa3563-502e-4205-bcb8-3e04875a5b8d" unselectable="on" style="display:none"></div></div> <p><br />Text: Mia Malmstedt<br />Photo and video: Johan Bodell<br />Illustration: Yen Strandqvist </p>Mon, 16 Apr 2018 09:00:00 +0200 Fager is Supervisor of the Year<p><b>​Chalmers Research Supervisor of the Year 2017/2018 Award is granted to Christian Fager, Professor at the department of Microtechnology and Nanoscience – MC2.</b></p><div><span style="background-color:initial">The award committee has chosen to grant Christian Fager the award for his constant work on refining his supervision skills for his many PhD students.

In a new grant from the ERC (European Research Council), Professor Andrew Ewing has received 25 million to chart the role of secretion of neurotransmitters in our memory process.</b></p><p>​Signal substances in the brain are the molecules that cells use to communicate and send nerve signals to each other. The cells contain capsules, so-called vesicles, which are filled with a certain amount of transmitter molecules, so-called signal substances, used by the cells for communication and regulatory functions in the organism.</p> <p><br />Our short-term memory starts with a chemical process in the brain where brain cells interact with the aid of neurotransmitters that are secreted from these vesicles. The cellular processes that direct the vesicle to start release have been charted and the 2013 Nobel Prize in Physiology and Medicine was given for this. Exactly how this finishes is, however, not known today, but earlier results from Andrew Ewing’s research show that the amount of signal substance that cells emit varies in different situations providing a mechanism for change in signal or learning. By examining the content of signal substance in individual vesicles and comparing to the amount of signal substance that a cell yields, his research shows that it is possible to see at a very detailed level how much signal substance is released from the cell in different situations. </p> <p><br />&quot;This discovery provides a completely different view of what regulates neurotransmitter release and shows this regulation is possible at the level of single release events.&quot;</p> <p> <br />Knowledge of this opens up for further research on the transmission of signal transmission and raises questions about the plasticity of the cell wall and how strong the coupling, synapse, between the nervous cells, which can lead to methods that may counter memory diseases.</p> <p><br />&quot;This can give us tools to understand the processes that are affected in diseases, such as Alzheimer's disease, adding a new pharmaceutical target by regulating individual vesicles and how they open.&quot;</p> <p><a href="/en/Staff/Pages/andrew-ewing.aspx"><br />Andrew Ewing</a> has now received an estimate of 2.5 million euro from the ERC to test how extensive the proposed mechanism is, to develop new methods of analysis of nanometer vesicles, and to use this in a next step to investigate full brain cells of banana flies as a model. In addition, he will investigate the role of changes in the membrane of the cell in the chemical reactions that are essential for a functioning short-term memory.</p> <p><br />&quot;I have been blessed with being able to interact with great students, postdocs and collaborators with open minds and super ideas. ​This is a very exciting and far reaching project where many of the things we are investigating are clearly controversial and parts might not work, but that adds to the excitement and this is the kind of work the ERC funds to push science to the future.&quot;</p> <p><br />In the long run, Andrew Ewing hopes that his research will provide tools to understand how diseases that damage short-term memory work on a deeper level.</p> <p> </p> <p>Text: Mats Tiborn</p>Fri, 06 Apr 2018 00:00:00 +0200 kickoff for new center in quantum technology<p><b>​The starting signal for the Wallenberg Center for Quantum Technology (WACQT) has been fired.

Most of the money come from Knut and Alice Wallenberg Foundation, which contributes with 600 million. The rest comes from Chalmers University of Technology Foundation, and the cooperating universities in Lund, Linköping and the Royal Institute of Technology (KTH). The goal is to build a Swedish quantum computer in ten years and to build competence in quantum technology in Sweden.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/wacqt_kickoff_665x330a.jpg" alt="picture link to article" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">Collaboration with business</h5> <div>The idea is also to start collaborations with industry in different areas. At the kickoff there were representatives from about ten companies like Astra Zeneca, Ericsson and IBM.</div> <div>&quot;We want to reach both smaller and larger companies, including those who do not currently work with quantum technology. Companies will have the opportunity to influence the focus of research based on their needs. Let's say that a company wants to develop a certain pharmaceutical and simulate that, then we can adopt our quantum computer so that it makes it more useful to simulate a certain type of drug. In this way, we can adapt to make it more interesting for companies to cooperate with us,&quot; says Per Delsing (picture above), who heads WACQT.</div> <div>In Chalmers offering to companies there are opportunities for industrial PhD:s, advanced courses in quantum technology and invitations to workshops. It will also be possible to acquire licenses and establish intellectual property agreements for the research results. Conversations with companies will begin in the spring.</div> <div>On 14 March, on the second day of the kickoff, there was also a special program point where companies were given the opportunity to present themselves and their wishes. In the entrance hall at Kemivägen 9 was a poster exhibition with several participating universities. There was also the opportunity to accompany guided lab tours.</div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/wacqt_kickoff_665x330e.jpg" alt="picture link to article" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">Exciting trip </h5></div> <div>The goal of the center effort is to take Swedish research and industry to the front of the second quantum revolution.

Since April 2017 Witlef Wieczorek, assistant professor at the Quantum Technology Laboratory at MC2, has been planning and building a new laboratory with equipment, researchers and doctoral students. &quot;The infrastructure and the people who do research here at Chalmers and particularly at MC2 are impressive&quot;, he says.</b></p> <div>Witlef Wieczorek was originally hired as an assistant professor at the Quantum Device Physics Laboratory, but since 1 January 2018 he is a member of the newly established Quantum Technology Laboratory. He welcomes us to his new office in the MC2 building at Chalmers. The corridor on the fourth floor is the location of a brand-new research laboratory within Mechanical Quantum Devices in 2018, headed by Witlef. New instruments and machines are installed in the renovated facilities, which previously were used by Thorvald Andersson and his legendary MBE Group.</div> <div>&quot;Kaija Matikainen and Svante Pålsson from MC2 and Linus Andersson from Bength Dahlgren are important key persons for me, among many others. They help a lot with the lab space. Kaija was essentially in charge of the renovation of the office space. Mikael Fogelström and August Yurgens showed continued support for this renovation&quot;,  Witlef says.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/witlef_300px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Two PhD students have already started in his lab, and more people are yet to come to work on different projects related to mechanical quantum devices. Witlef also welcomes interested master students to the new environment. Lots of new instruments are ordered and installed during the previous and upcoming months:</div> <div>&quot;Yes, an optical table like what photonics people have, a cryostat, a laser, optical modulation equipment, and some electronics equipment such as a frequency generator, a spectrum analyzer, an oscilloscope... and much much more&quot;, Witlef mentions, counting on his fingers.</div> <div> </div> <div>To set up a new laboratory is a complicated process which can take up until a year before it's alive and kicking.</div> <div>&quot;When all the equipment is there,  we have to make it work: connect, test and programme everything and then order the small things which we might have forgotten. Most of the time I buy new equipment, but sometimes it's possible to buy used one. Overall, it takes a lot of time until a lab is running. The good thing is that MC2 has an excellent cleanroom, so you can always work on fabricating your samples! The support from the cleanroom people is really wonderful. I'm very happy about it.&quot;</div> <div> </div> <div>Witlef Wieczorek was born in Berlin in 1979. </div> <div>&quot;I am born in the eastern side. If the Berlin wall hadn't fallen I wouldn't be here&quot;, he says.</div> <div>He now lives in a rented house in Västra Frölunda, together with his family; wife and two daughters, aged six and three years. The family has accustomed well to the new life in Gothenburg.</div> <div>&quot;We are all quite happy. My oldest daughter is going to preschool, and  she likes it very much. But in the beginning it was a bit hard, because of language and so on.&quot;</div> <div> </div> <h5 class="chalmersElement-H5">Do you like Gothenburg?</h5> <div>&quot;Yes! We like it very much. We have never lived close to the sea before and we currently really enjoy that. Every time the weather permits we take the ferries and go to the archipelago with the kids. We like to go and see nature, we use our bicycles quite a lot. Gothenburg is also a city that we can nicely explore with our kids, for example, all the family-friendly museums.  And, there's still a lot more to explore.&quot;</div> <div> </div> <div>Witlef's father was a physicist in Berlin. In his childhood, Witlef became interested and started to study physics too.</div> <div>&quot;At some point I thought I had to move out of the city, so I decided to go to Munich to do a PhD. It also came along with my interest in quantum physics and quantum optics.&quot;</div> <div>In Munich, Witlef became a member of the well-known Weinfurter Group at the Ludwig-Maximilians-Universität München (LMU University of Munich) and at the Max Planck Institute of Quantum Optics in Garching, Germany.</div> <div>&quot;Then I started to do experiments on entangled photons, studying the weird predictions of quantum physics&quot;, Witlef tells us.</div> <div>He did his experiments at the Max Planck Institute.</div> <div>&quot;The idea of the research was essentially to study quantum information, to explore quantum information, to understand it a bit better by using the physical system of light or photons. It goes along at what Per Delsing and Göran Johansson are doing here; they're using superconducting qubits and now they want to build a quantum computer.&quot;</div> <div> </div> <h5 class="chalmersElement-H5">Tell us a bit about your PhD thesis!</h5> <div>&quot;My PhD was rather a bit more basic in the sense that I wanted to understand entanglement of multiple objects. We were quite successful in that respect, at that time it was really good to entangle six photons, and we could show that and analyze that.&quot;</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/witlef_IMG_0353_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />One day Witlef attended a lecture with Professor Markus Aspelmeyer from the Aspelmeyer Group at the University of Vienna. He is a pioneer in studying quantum objects with mechanical systems. The talk was so inspiring that Witlef felt that he wanted to do his PostDoc in his group. He got approved and moved to Vienna. </div> <div>His years in Vienna awaken thoughts to some day start his own research group.</div> <div>&quot;I thought that I sometime in my life wanted to do my own experiments and pursue my own ideas. That brought me here!&quot;, Witlef says.</div> <div> </div> <div>In 2016, Witlef Wieczorek applied for a position at MC2, when he got aware of a call for an assistant professorship in the Nanoscience and Nanotechnology Area of Advance. And in April 2017 he began his new appointment. Recently he switched to the newly established Quantum Technology Laboratory at MC2. </div> <div>&quot;I am really happy to be here. Definitely because of the research. The infrastructure and the people who do research here are impressive, the possibilities to interact and collaborate are excellent, and everybody's is very open. Another reason to go here is to learn a new language, I have started to learn Swedish!&quot;</div> <div> </div> <div>In his spare time, Witlef enjoys playing basketball, he was a skilled player once, and, of course, being with his family. He also likes beachvolleyball and literature. Among his favourite authors are Herman Hesse and José Saramago:</div> <div>&quot;Saramago has amazing sentences that go over one page, one has to get into that, and his books are really enjoyable, &quot;Blindness&quot; is very good for example. I also like &quot;The Gospel according to Jesus Christ&quot;, which is a very nice book.&quot;</div> <div> </div> <div>Text and photo: Michael Nystås</div> Thu, 18 Jan 2018 10:00:00 +0100 researcher strengthens the quantum computer project<p><b>​The goal is to build a large quantum computer within ten years. But the task is extremely complicated and Chalmers University of Technology needs to recruit world-class expertise in a number of fields. First up is Giulia Ferrini – an expert in quantum computations in continuous variables.</b></p>The beginning of the year marked the launch of the Wallenberg Centre for Quantum Technology – a SEK 1 billion initiative to set Sweden on course to a global top position in quantum technology. The focus is on developing a quantum computer with much greater computing power than the best supercomputers of today; read more in <a href="/en/news/Pages/Engineering-of-a-Swedish-quantum-computer-set-to-start.aspx">Engineering of a Swedish quantum computer set to start</a>.<br /><br />Only a few days after the starting pistol was fired the theoretical physicist Giulia Ferrini is in place in her new university, Chalmers, where she is an eagerly awaited part in the quantum computer project.<br />“It’s amazing to become part of this adventure! Sweden is one of the places I would like to live. I like the culture and the society is advanced – it feels like living in the future”, says Ferrini, who was previously a Marie Curie fellow at the University of Mainz in Germany.<br /><br />As a physics student, she was amazed by the strange phenomena of quantum physics and this aroused her interest in quantum information. She is attracted by the potential of using the peculiarities of quantum physics to create practical benefits in the form of new technology, while this also gives her an excuse for exploring the fundamentals of quantum physics.<br />“I’m very curious. I like to start from an intuitive idea and then do the hard work required to formalise it and come up with proof or a model that others can test in the lab”, explains Ferrini.<br /><br />She is mainly interested in encoding quantum information in continuous variables such as in an electromagnetic field. The other main thrust in quantum computers is to encode information in what are known as qubits, with two quantum states representing zero and one. Both methods have their advantages and disadvantages, but so far Chalmers has focused mainly on qubits.<br />“Nobody knows yet what will work best in the end, and we need to know both methods. With Giulia Ferrini we are acquiring completely new expertise which fits very well with our own,” says Göran Johansson, Professor of Applied Quantum Physics, and one of the principal investigators in the quantum computer project.<br /><br />First of all, Ferrini together with Johansson will investigate and evaluate a new proposal on how to design a superconducting quantum computer, published by researchers in Canada. In parallel with this she will study where the boundary lies between what a standard computer and a quantum computer can do. The aim is to develop a criterion for what the minimum requirements are to achieve what is known as quantum supremacy, in other words to reach the point at which a quantum computer outperforms a standard computer.<br /><br />Two doctoral students are on their way in and Ferrini is looking forward to starting to build a research team, as well as collaborating both with the experimentalists at Chalmers and with other groups.<br />“Collaboration is fun and important for getting new ideas so that you can do relevant research,” says Ferrini.<br /><br />Beyond research, dance – in different styles – is her great interest. She describes herself as distinctly a city person, but has noticed that she appreciates the green space outside her new home in Gothenburg. In addition to finding a good place to dance, exploring the Swedish countryside is now also high up on her list.<br /><br />Text: Ingela Roos<br />Photo: Johan Bodell<br /><br />Read more about quantum computers in <a href="/en/news/Documents/quantum_technology_popdescr_171114_eng.pdf">Quantum technology – popular science description</a><br /><br />Read more about the <a href="/en/centres/wacqt/Pages/default.aspx">Wallenberg Centre for Quantum Technology</a><br />Tue, 16 Jan 2018 10:00:00 +0100 for the Master&#39;s programme in Nanotechnology<p><b>​Erasmus Mundus international Nano+ programme – of which Chalmers Master&#39;s programme Nanotechnology is a part – has been granted three million euros for the period 2018-2022. At the same time, the programme has received the prestigious stamp &quot;Success Story&quot; by the European Commission. &quot;We are very proud and happy about it,&quot; says Thilo Bauch, local coordinator for the Erasmus students.</b></p>Thilo is an associate professor at the Quantum Device Physics Laboraory at MC2. We meet him and his colleague Elsebeth Schröder, who is professor at the same laborary and since 2013 also coordinator of the Master's programme Nanotechnology.<br /><br />Erasmus Mundus Nano+ (EMM-Nano+) is the name of a collaboration between Chalmers, KU Leuven in Belgium, University Grenoble Alpes in France, TU Dresden in Germany and University Barcelona in Spain. The higher education institutions cooperate with their respective Master's programmes in Nanotechnology. The collaboration has been in effect since 2005. Chalmers has been involved since the start of the its own Master's programme Nanotechnology. At most, 19 Erasmus students have been in studying in Gothenburg, a record achieved two years ago.<br /><br />The arrangement means that the students study their first year at KU Leuven in Belgium, and the second year at one of the other four co-operating universities. A number of students then choose to come to Chalmers. At the Nanotechnology program they read together with the existing students. Course packages are also tailored partly because the students also study some courses normally given during the first year of the programme.<br />Internal evaluations show that the teachers are very pleased with the Erasmus students:<br />&quot;The students who choose Chalmers handle the courses very well. They have a good height in their knowledge. It is of course pleasing that some of them choose to come here,&quot; says Elsebeth Schröder.<br /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/tbauch_220x180.jpg" class="chalmersPosition-FloatLeft" alt="Link to news article." style="margin:5px" />Thilo Bauch acts as local coordinator for the Erasmus students. This means that he has a special responsibility for taking care of them on site, giving them scientific advice and keeping in touch with KU Leuven, who coordinates the programme.<br />&quot;The assignment is 15%. There is a lot of administration, but also teaching. I am attending the Erasmus Nano Board, which meets three times a year. I am also co-arranging a workshop for the Chalmers students every three years, most recently in 2016,&quot; Thilo says.<br />The workshop is ongoing for five days and one important feature is the display of the Nanofabrication Laboratory, which is usually handled by Ulf Södervall.<br /><br /><span><img src="/SiteCollectionImages/Institutioner/MC2/News/eschroder_220x180.jpg" class="chalmersPosition-FloatLeft" alt="Link to news article." style="margin:5px" /></span>Now that the European Commission grants additional funding of three million euros, it is a larger amount than before. The money goes to scholarships and pays tuition fees and accommodation for 58 students, distributed on the four partner universities and three rounds.<br />&quot;It feels really good that we can continue. The international students are a good addition to the local nanostudents. They add very much and are really aware of what they want, because they have made an active choice to come here. It's no random choice. It's good that they come into the environment here,&quot; Elsebeth says.<br /><br />The students come from all over the world. Thilo Bauch has an active part in the selection. Together with colleagues from all partner universities, he reviews all applications during a two-day marathon session in Leuven every year. A sweaty job that involves accepting students already for the first grade in Belgium.<br /><br />The Commission also shows its appreciation by giving the EMM Nano+ the stamp &quot;Success Story&quot;, as one of only six designated success programmes, of a total of 376, in the last ten-year period. The stamp embraces programmes  that &quot;have distinguished themselves by their impact, contribution to policy-making, innovative results or creative approach, and can be a source of inspiration for others.&quot;<br />In addition, the Commission also has assigned the program the rating &quot;good practice&quot; to &quot;particularly well managed and inspiring&quot; programmes.<br />&quot;Not only did you assess the actual education, but also everything from the application process, how we choose the students, what activities are offered locally, to how we work with integration, are being examined. Chalmers contributes a lot to this success stamp,&quot; says Thilo Bauch.<br /><br />The new grant and quality stamp increase the attractiveness of the programme.<br />&quot;It also gives us many good candidates for our PhD positions. Many students remain and begin a postgraduate education,&quot; says Thilo Bauch.<br />Since its inception, approximately 350 students from 55 countries have been examined in the EMM Nano+ programme.<br /><br />Text and photo: Michael Nystås<br /><br /><a href="">Read more about the EMM Nano+ programme</a> &gt;&gt;&gt;<br /><br /><a href="">Read more about the Nanotechnology Master's programme at Chalmers</a> &gt;&gt;&gt;<br />Wed, 20 Dec 2017 09:00:00 +0100 recruitment event at MC2<p><b>​Over 100 potential doctoral students and thesis workers participated when MC2 hosted a major recruitment and information evening on 13 December. &quot;Very nice that so many showed interest in the opportunities for a career with us,&quot; says Mikael Fogelström, Head of the Department.</b></p><div>It was a real smorgasbord that appeared in the canyon when the department gathered forces to tell about all the offers available. The focus was on existing and future PhD vacancies, but students who were interested in doing their Master's thesis on MC2 were welcomed as well.</div> <div>In front of a crowded Kollektorn, Göran Johansson, Peter Andrekson and Christian Fager held short TED-inspired presentations. In the open space outside the auditorium there was opportunities to mingle with researchers and representatives from the HR department, and to get even more information in a mini exhibition. There were also a number of well-visited lab tours, including MC2's high-tech cleanroom, the Nanofabrication Laboratory.</div> <div> </div> <div>MC2's head Mikael Fogelström is very pleased when he summarizes the successful event:</div> <div>&quot;It was very fun that so many students showed interest and came. Our presenters in Kollektorn did an excellent job. It was also nice that it became such an active mingle,&quot; he says.</div> <div> </div> <div>Fogelström also praises all the others involved; HR representatives, PhD students, researchers and teachers on site, and the management team who organized the event, with Cristina Andersson, Susannah Carlsson and Debora Perlheden at the forefront, and with Karin Kjell as HR support.</div> <div>&quot;All honors to those who implemented it all. It shows that we have a good structure and a functioning organization. We will certainly arrange this more times,&quot; says Mikael Fogelström.</div> <div> </div> <div>Text: Michael Nystås</div> <div>Photo: Susannah Carlsson</div> <div><br /></div>Thu, 14 Dec 2017 11:00:00 +0100
