News: Centre WACQT related to Chalmers University of TechnologyFri, 09 Oct 2020 09:42:28 +0200 program to stop the leaky pipeline of academia<p><b>​28 mentees and 28 mentors have just started their journey together in a brand-new mentoring program at Chalmers University of Technology. The purpose is to support female researchers in their personal and professional development, and to create good connections between junior and senior academic women.</b></p>​​<span style="background-color:initial">The mentoring program is an initiative by the two networks WiSE (Women in Science, based at the Department of Electrical Engineering), and WWACQT (Women in WACQT, within the Wallenberg Centre for Quantum Technology). The program is supported by the Gender Initiative for Excellence at Chalmers, Genie.</span><div><br /></div> <div>“Our aim is primarily to promote personal and professional development for female PhD students and postdocs. The mentoring program will provide a framework for discussing challenges and problems in everyday research life, and thus foster an environment to make wiser career choices. Networking is a key component”, says Giulia Ferrini, representing WWACQT in the organizing committee of the mentoring program.</div> <div><br /></div> <div>The program was launched at a digital kick-off on 25 September.<br /></div> <div><br /></div> <div><strong>Provide guidance through ups and downs</strong></div> <div><span style="background-color:initial">“We have wanted to start a program like this for many years”, says Hana Dobsicek Trefna from WiSE who held the introduction at the meeting. “As a junior in academia you soon realize that you need a role model that can provide new perspectives and guide you through the ups and downs of life. We are very pleased that this pilot finally is becoming a reality.”</span><br /></div> <div><br /></div> <div>Academia is a leaky pipeline in the sense that many female researchers drop off to seek other career opportunities, before reaching senior positions. This is especially true in the technical fields, and that is also one of the reasons why the networks WiSE and WWACQT were founded, in 2011 and 2019 respectively. </div> <div><br /></div> <div>“My lesson learned over the years is that support from different persons and constellations means a lot, both at work and in life. Based on this, I especially want to emphasize the importance of what you do in WWACQT, WiSE and Genie, and what a mentoring program can accomplish”, said Lena Gustavsson, professor emerita, in her keynote speech at the kick-off meeting.</div> <div><br /></div> <div><strong>Advice for mentees and mentors</strong></div> <div>Lena Sommarström, study and career guidance counsellor, experienced in organizing student mentor programs at Chalmers, shared her best practices for mentors and mentees. </div> <div><br /></div> <div>“As a mentee, you should first ask yourself what you think you need to develop, and then share your thoughts with your mentor. Accepting the role as a mentor is an excellent opportunity for a senior person to further develop communications skills, practice active listening and mirror herself as a role model,” she said.</div> <div><br /></div> <div>The participants also got the opportunity to meet for the first time in their new roles and say hello digitally to their match. </div> <div><br /></div> <div>“I joined the program because I think it's valuable to hear tips and experiences from older and wiser colleagues”, says Marina Kudra, a mentee in the program and a doctoral student at Microtechnology and Nanoscience, who has found her match in Silvia Muceli, assistant professor at Electrical Engineering. “The fact that my mentor is a female I consider a big plus. She can help me see which challenges and advantages academia has to offer. I am looking forward to the journey.&quot;</div> <div><br /></div> <div>In its first phase the program will run for one year and will then be evaluated. The participants are encouraged to continue their relations as long as the dialogue is rewarding and fruitful.</div> <div><br /></div> <div>Text: Yvonne Jonsson<br />Photo: Susannah Carlsson</div> <div><br /></div> <div><div><a href="/en/about-chalmers/Chalmers-for-a-sustainable-future/initiatives-for-gender-equality/gender-initiative-for-excellence/Pages/Wise-Wwacqt%20mentorship/WiSE-WWACQT-Mentorship-Program.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the mentorship program</a></div> <div><a href="/en/departments/e2/network/wise/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read about WiSE - Women in Science</a> </div> <div><a href="/en/centres/wacqt/Pages/Women-in-WACQT.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read about WWACQT - Women in WACQT, within the Wallenberg Centre for Quantum Technology</a></div></div> <div><a href="/en/about-chalmers/Chalmers-for-a-sustainable-future/initiatives-for-gender-equality/gender-initiative-for-excellence/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read about Genie - <span style="background-color:initial">Gender Initiative for Excellence </span>​</a></div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/WACQT/WiSE+WWACQT%20logo.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:400px;height:120px" /><br /><br /><br /></div> <div></div>Wed, 07 Oct 2020 00:00:00 +0200 exclusive student conference in quantum technology<p><b>​Participants from some 30 countries are expected to attend Berlin when the Quantum Future Academy 2020 (QFA2020) is organized on 1-7 November.

Travel, accommodation and living are fully reimbursed.<br /><br />QFA2020 will take place in Berlin. However, Göran Wendin points out that the organizers are closely following the development of the corona pandemic, and that all safety procedures will be followed.<br />&quot;All participants will receive detailed information in good time about any changes,&quot; he says.<br /><br />The application is open until 24 July for all interested students at the bachelor's or master's level with basic knowledge in quantum mechanics. In Sweden, the winners will be presented at a digital workshop at Chalmers in mid-September, where all applicants will present their ideas.<br /><br />The conference week in Berlin in November has a packed content. It will include study visits to companies and research laboratories, lectures, meetings with researchers, politicians and entrepreneurs, workshops and even cultural activities.<br />&quot;We can promise an exciting and exclusive week in Berlin,&quot; concludes Göran Wendin.<br /><br />Text: Michael Nystås<br />Photo: Johan Bodell<br /><br /><strong>Contact:</strong><br />Göran Wendin, Professor, Quantum Technology Laboratory, Wallenberg Centre for Quantum Technology (WACQT), Department of Microtechnology and Nanoscience <span>–<span style="display:inline-block"></span></span> MC2, Chalmers,<br /><br /><div><span><strong>Read more about Quantum Future Academy 2020 (QFA2020) &gt;&gt;&gt;</strong><br /><a href="/en/centres/wacqt/qfa2020"></a> and also<br /><a href=""></a> <br /><br /><strong><a href="/en/centres/wacqt">Read more about Wallenberg Centre for Quantum Technology (WACQT)</a> &gt;&gt;&gt;</strong><br /><br /><a href="">Läs mer om Read more about the EU flagship in quantum technology </a>&gt;&gt;&gt;<span style="display:inline-block"></span></span><br /></div>Fri, 03 Jul 2020 09:00:00 +0200 structures enable deep tissue imaging of blood oxygenation<p><b>​​Imaging of the blood oxygenation inside the body would be a useful tool for fast diagnosis of conditions like stroke and heart failure. However, it has so far been prevented by the fact that body tissue scatters light in all directions. A research team within the Wallenberg Centre for Quantum Technology now make use of a crystal with tailored quantum structure to solve the problem.</b></p>​<span style="background-color:initial;font-size:14px">More than 30 % of the patients seeking emergency care have symptoms related to reduced blood oxygenation, possibly indicating stroke, heart failure or similar conditions. Therefore, it would be advantageous to be able to image the oxygenation in the body. It is known that deoxygenated blood absorbs red light of a specific wavelength (700 nanometres) to a much greater extent than oxygenated blood. Measuring the light absorption at that wavelength can thus reveal the oxygenation level. Unfortunately, body tissue scatters the light in all directions, making it impossible to tell where the absorption took place.</span><span></span><div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">A research team within the Wallenberg Centre for Quantum Technology (WACQT) now tries to solve this problem by pointing an ultrasound pulse to the location to be measured. The ultrasound shifts the wavelength of the light by a small amount, and by analyzing the wavelength-shifted light for different positions of the ultrasound pulse, they expect to be able to form an image of the oxygenation level. In order to filter out the tiny amount of wavelength-shifted light from the much stronger unshifted light, they use a crystal with a specific quantum structure designed by the Quantum Information Group at Lund University. The crystal strongly suppresses light at the unshifted wavelength – and also slows down the shifted light to just a few kilometres per second.</span></div> <div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">“This means it comes out long after any remaining unshifted light, and effectively can be distinguished from it,” says principal investigator Stefan Kröll.</span></div> <div><span style="font-size:14px">In this way, the team has managed to achieve measurements almost free from background noise, as described in an <a href="" target="_blank">article in Biomedical Optics Express​</a>. The technique is developed by industrial PhD student David Hill at the medical start-up company SpectraCure AB together with the Quantum Information Group at Lund University.</span></div> <div><br /></div> Fri, 15 May 2020 10:00:00 +0200 demonstration of useful quantum algorithm<p><b>​Being able to solve a useful problem on a quantum computer – and ideally much faster than on a conventional computer – is future milestone that many researchers dream of.

In just minutes, their quantum computer performed a computational task that, according to the researchers, would have taken more than ten thousand years for a powerful supercomputer. Göran Johansson, one of the leaders of Chalmers quantum computer project, sees this as a major milestone.</b></p><div><span style="background-color:initial"><strong>How did you feel when you heard of the news?</strong></span><br /></div> <div>“I felt very happy! I knew that Google's research team was starting to get results with their 53-qubit quantum computer Sycamore, but that they have now managed to get such good reliability in their operations that they can perform this kind of calculation – it's a fantastic breakthrough!”</div> <div><br /></div> <div><strong>What lies behind the breakthrough?</strong></div> <div>“Sycamore is quite similar to Google's previous quantum computers in its structure. The breakthrough rather results from careful design of the hardware and software used to control the chip and a thorough analysis of which computational task to choose.”</div> <div><br /></div> <div><strong>Does this mean that quantum computers now outperform regular computers in general?</strong></div> <div>“No, absolutely not. The research team has shown that their quantum computer can solve a single calculation task better than a regular computer. The solved task is completely useless, it was chosen solely because it was judged to be easy to solve for a quantum computer but very difficult for a conventional one. But as quantum computers evolve, they will outperform conventional computers in more and more types of tasks.”</div> <div><br /></div> <div><strong>IBM criticizes Google’s calculations and states that their best supercomputer could solve the task in less than three days. What do you think about that?</strong></div> <div>“If that is the case, it would still be the first time a quantum computer performs something that requires the full capacity of the world's largest supercomputer, for almost three whole days, to reproduce. Whether it's ten thousand years or three days, I see the achievement of Google’s team as a very important step forward.”</div> <div><br /></div> <div><strong>What does this breakthrough mean to Chalmers quantum computer project?</strong></div> <div>“We are aiming for a quantum computer with one hundred well-functioning qubits, and Google has now shown that it is possible to create over fifty qubits that operate at over 99 percent reliability. It is incredibly inspiring and motivating!”</div> <div><br /></div> <div><strong>How does your quantum computer compare to Google’s?</strong></div> <div>“We use the same basic building blocks – superconducting circuits – as Google. So far, we are working, completely according to our plan, with a chip with only two qubits. Our strategy is to first get it to work really, really well on a small scale. For example, Google's qubits have an average lifetime of 16 microseconds, while we have over 80 microseconds. The longer the lifetime, the more computational operations you can do. On the other hand, Google has managed to reach significantly faster operations than we have, but we are working at getting really good at that as well. Then we will start to scale up in fairly large steps.”</div> <div><br /></div> <div><strong>What will be the next milestone in the development of quantum computers?</strong></div> <div>“Finding a useful problem that is beyond the reach of ordinary computers, but which a quantum computer with fifty to a hundred qubits can solve. We work intensively on this in collaboration with our industry partners. Probably, it will be within logistics or simulation of large molecules.”</div> <div><br /></div> <div>Text: Ingela Roos</div> <div>Photo: Johan Bodell</div> <div><br /></div> <div>The article has previously been published in Swedish in Chalmers magasin #2 2019</div> <div><br /></div> <div><a href="/en/centres/wacqt">Read more about Wallenberg Centre for Quantum Technology​</a> &gt;&gt;&gt;</div>Wed, 18 Dec 2019 09:00:00 +0100 scientist becomes Wallenberg Academy Fellow<p><b>Witlef Wieczorek, Assistant Professor at the Quantum Technology Laboratory at MC2, has been honoured with a prestigious Wallenberg Academy Fellow assignment. &quot;It feels just great and I am overwhelmed by this decision and award,&quot; says Witlef.</b></p><div><div>The Wallenberg Academy Fellow is a five-year grant which provides young researchers with opportunities to make important scientific breakthroughs by providing long-term research funding in Sweden.

Though, such a state of a cat is in principle allowed by the laws of quantum mechanics, we have never observed superposed cats. The current record in superposition size is held by impressive experiments that observe the interference of large molecules. My project aims to superpose 10 million times heavier objects. This goal is ambitious! Therefore, we construct a novel experimental platform that should make this possible: levitated micrometer-sized superconducting objects that are coupled to superconducting circuitry,&quot; he explains.</div> <div> </div> <div>The Knut and Alice Wallenberg Foundation is announcing 29 new Wallenberg Academy Fellows on 3 December 2019.

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><a href=""><br />​</a>The first quantum revolution took place in the 20th century, <span><span><span><span><a href="/SiteCollectionDocuments/Centrum/WACQT/CM_15082018_Quantum%20technology_EN.pdf"><img src="/SiteCollectionImages/Institutioner/MC2/WACQT/EN_Quantum%20technology_750x446px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:300px;height:178px" /></a></span></span></span></span>when one learned to utilize quantum mechanical properties of light and material. This led, among other things, <span><span></span></span><span><span><span><a href=""></a></span></span></span>to the<span><a href=""></a></span> 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 is to 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 build a quantum computer. The smallest building block of the quantum computer – the quantum bit or qubit – 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 qubits. To surpass the computational power of today's supercomputers, it's enough with 50-60 qubits. The Chalmers researchers aim at reaching at least one hundred qubits 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 qubits for almost 20 years and delivered many contributions to knowledge building within the field. Now they are going to scale up and get many qubits to work together.</div> <div><br /></div> <div>At the lab, they are currently working to improve the lifetime of single qubits. Quantum states 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 will be quickly absorbed. They are also investigating and evaluating different strategies for coupling qubits 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 coupling of qubits, the number of qubits 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 become very expensive,&quot; explains Delsing.</div> <div><br /></div> <div>In order for the project to get initiated advice, they are in the process of setting up a scientific advisory 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 will be a sounding board that we can discuss complex issues with, for instance how fast we should scale up the number of qubits. 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 quantum computing 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 people,&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 properties which are important in the model at an early stage, so we don't include too many details when scaling up. Otherwise, we'll hit the ceiling for what a supercomputer can simulate before we reach 40 qubits,&quot; says Göran Johansson.</div> <div><br /></div> <div>Another important task for the theorists is to explore what a smaller quantum computer can do. With eight thousand well-functioning qubits, one could run the so-called Shor's algorithm – which aroused the world's interest in building quantum computers <span style="background-color:initial">–</span><span style="background-color:initial"> 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.</span></div> <div></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 kind of problems <span style="background-color:initial">– </span><span style="background-color:initial">that someone is interested in knowing the answer to </span><span style="background-color:initial">– a hundred qubit quantum computer can solve</span><span style="background-color:initial">,&quot; says Göran Johansson.</span></div> <div></div> <div><br /></div> <div>Here, industrial collaboration comes into the picture <span style="background-color:initial">–</span><span style="background-color:initial"> from companies, 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.</span></div> <span></span><div></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 speed 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.

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.

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
