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 seminar brings together world-leading researchers from several science disciplines to present the latest advances within the field.</b></p>​ <br />The conference gathers distinguished researchers, industry representatives, decision makers and an engaged public for presentations and discussions on future energy solutions. Development of sustainable technologies for solar energy, batteries and energy storage is needed to make the necessary switch from fossil fuels to renewable energy sources. During the conference, the latest advances in the field will be highlighted, and the content will be made available to the public. Through live broadcast at <a href="" target="_blank">Molecular Frontiers YouTube Channel</a>  you will be able to follow the conference even if you are not in place. <br /><br /><br /><strong>150 high school students participate</strong><br />Sustainable Energy Symposium is a unique event in several ways – about half of the conference participants are high school students. This is possible thanks to the Molecular Frontiers Foundation which offers a scholarship for students from all over the country to come. The Molecular Frontiers emphasize in particular the importance of being curious and asking good questions. Approximately 150 students from all over the country are given the opportunity to listen to and ask questions to world-leading researchers.<br /><br /><br />Among the speakers are noted:<br /><br /><strong>Steven Chu, Nobel Prize winner in Physics 1997 and Obama's Energy Ministers 2009-2013.</strong><br />Steven Chu was awarded the Nobel Prize in Physics in 1997 for his work on laser cooling of atoms. Since then, his research has increasingly been about solving the challenges of climate change and sustainable energy supply. In 2009, Barack Obama appointed him the United States Secretary of Energy, and became the first scientist in an American government. After his time as Energy Secretary, he returned to research but remains a prominent debater focusing on renewable energy and nuclear power. He emphasizes the importance of reducing fossil fuel use to address global warming and climate change. He has put forward a number of innovative and sometimes controversial proposals for action.<br /><br /><strong>Paul Alivisatos, University of California at Berkeley</strong><br />Paul Alivisatos is a pioneer in nanotechnology, focusing on inorganic nanocrystals. By controlling the size and surface of the nanocrystals, his research team can tailor their properties and produce materials for a variety of applications, including solar cells and materials to reduce carbon dioxide into hydrocarbons. He has developed quantum dots, small semiconductors that are isolated from the environment and are extremely effective in absorbing and transmitting light. These are already used in the most energy efficient and high quality television screens in market today.<br /><br /><strong>Daniel Nocera, Harvard University</strong><br />Two inventions of Daniel Nocera may be of great importance in the future. The artificial leaf, mentioned in Time magazine’s list of Inventions of the Year 2011, mimics the photosynthesis, and splits water into hydrogen and oxygen by using sunlight. A further development of the concept is the bionic leaf, which takes carbon dioxide from the air and combines it with hydrogen from the artificial leaf to produce biomass and liquid fuel. In this way, a cycle is achieved that is much more efficient than photosynthesis in nature, which can contribute to a green and cheap production of fuel and food.<br /><br /><br /><strong>Program</strong><br /><a href="/en/conference/sustainableenergy/Documents/Program_Sustainable_Energy.pdf" target="_blank">Here you will find the entire program for the conference &gt;</a><br /><br /><br />Plenary lectures 7-8 December:<br />• <strong>Steven Chu</strong> – <em>Climate Change and innovative paths to a sustainable future</em><br />Nobel laureate in Physics 1997, former United States Secretary of Energy.

It is the first of its kind, and can extend the use of terahertz technology to applications that will require flexible electronics, such as wireless sensor networks and wearable technology. The results are published in the scientific journal Applied Physics Letters.</b></p>Terahertz radiation has a wide range of uses and can occur in everything from radio astronomy to medicine. The term refers to the electromagnetic waves whose frequencies range from 100 gigahertz to 10 terahertz. Demand for higher bandwidth in wireless communications and depiction for security applications has led to intensified research on systems and components intended for terahertz frequencies.<br /><br />One challenge has long been to enable low weight and cheap applications. However, advances in polymer technology have promoted the development of flexible electronics and enabled the production of high frequency units on flexible substrates.<br /><br />Now, Chalmers researchers Xinxin Yang, Andrei Vorobiev, Andrey Generalov, Michael A. Andersson and Jan Stake have developed the first mechanically flexible and graphene-based terahertz detector in its kind. Thus, paving the way for flexible terahertz electronics.<br /><img src="/SiteCollectionImages/Institutioner/MC2/News/thz_detektor_171017_adj.jpg" width="629" height="435" alt="" style="margin:5px" /><br /><span class="FeaturedImageText"><em>​</em><span><em>With the help of the two-dimensional material graphene, the first flexible terahertz detector has been developed by researchers at Chalmers. Illustration: Boid – Product Design Studio, Gothenburg.</em><br /></span></span><br />The detector has unique features. At room temperature, it detects signals in the frequency range 330 to 500 gigahertz. It is translucent and flexible, and opens to a variety of applications. The technique can be used for imaging in the terahertz area (THz camera), but also for identifying different substances (sensor). It may also be of potential benefit in health care, where terahertz waves can be used to detect cancer. Other areas where the detector could be used are imaging sensors for vehicles or for wireless communications.<br /><br />The unique electronic features of graphene, combined with its flexible nature, make it a promising material to integrate into plastic and fabric, something that will be important building blocks in a future interconnected world. Graphene electronics enables new applications for, among other things, everyday objects, which are commonly referred to as the Internet of Things.<br /><img src="/SiteCollectionImages/Institutioner/MC2/News/detektor_forskarbilder_171030.JPG" alt="" style="margin:5px" /><br /><em>The research group behind the flexible terahertz detector, from the left </em><span><em>Jan Stake, Xinxin Yang, Andrei Vorobiev, Andrey Generalov and Michael A.

It is a feature that makes graphene an attractive building block in fast electronics. The Chalmers researchers' work is therefore an important step forward for graphene in the terahertz area, and a breakthrough for high performance and cheap flexible terahertz technology.<br /><br />The detector drew attention at the EU Tallinn Digital Summit recently, where several important technological innovations made possible by graphene and related materials were on display. At the summit, EU Heads of State and Government gathered to discuss digital innovation and Europe's digital future. The flagship focus was to show what role graphene can play.<br /><br />The research is also part of Xinxin Yang's licentiate seminar, which will be presented at Chalmers on 22 November 2017.<br /><br />The research on the terahertz detector has been funded by the EU Graphene Flagship, the Swedish Foundation for Strategic Research (SSF), and the Knut and Alice Wallenberg Foundation (KAW).<br /><br />Text: Michael Nystås<br />Illustration: Boid – Product Design Studio, Gothenburg<br />Photographs of Jan Stake, Xinxin Yang, Andrei Vorobiev, Andrey Generalov and Michael A.

The results pave the way for better nanomaterials and safer nanotechnology and were recently published in the journal Nature Communications.</b></p><div>In the future almost all new technology will be based on nanotechnology in some form. But nanoparticles are temperamental personalities. Even when they look the same from a distance, they are obstinately individual when you zoom in to each individual one.</div> <div>Chalmers researchers Svetlana Alekseeva and Christoph Langhammer together with Danish researchers at the Technical University of Denmark have discovered why different polycrystalline nanoparticles behave so distinctly when they come into contact with hydrogen. This knowledge is essential in order to develop better hydrogen detectors, which are expected to play an important role in the safety of hydrogen cars.</div> <div><br />“Our experim<span><img src="/SiteCollectionImages/Institutioner/F/Divisions/Chemical%20Physics/Staff/Sveta.jpg" class="chalmersPosition-FloatRight" width="125" height="161" alt="" style="margin:5px" /><span style="display:inline-block"></span></span>ents clearly showed how the reaction with hydrogen depends on the specifics of the way in which the nanoparticles are constructed. It was surprising to see how strong the correlation was between properties and response – and how well it could be predicted theoretically,” says Alekseeva, a postdoc at the Department of Physics at Chalmers.</div> <div><br />A nanoparticle of a certain material is comprised of a number of smaller grains or crystals. The number of grains and how they are arranged are therefore crucial in determining how the particle reacts in a certain situation or with a certain substance.</div> <div>Alekseeva and her collaborators have produced maps  – effectively virtual portraits – of individual palladium nanoparticles. The images show the grains as a number of fields which are combined into a map. Some particles consist of a large number of grains, others have fewer grains, and the fields border on one another in different ways.</div> <div><br /></div> <div>This new method of characterising nanoparticles is based on a combination of electron microscopy and optical microscopy. The same individuals are examined using both methods and it is possible to monitor their response when they encounter other substances. This therefore makes it possible to map the basic material properties of nanoparticles at an individual level, and see how these correlate with the response of the particles when they interact with their environment.<br />As a result an almost infinite range of possibilities are opened up for further research and for the development of products and nanomaterials which are both technically optimised and safer from an environmental and health perspective.</div> <div>The nanoparticles that have been investigated also operate as sensors in themselves. When they are illuminated, they reveal how they react with other substances, such as various gases or fluids. Langhammer’s research team is currently working on several projects in this area, including some relating to hydrogen detection.</div> <div><br />But knowledge about nanoparticles is needed in a range of different fields in society. These include, for example, in new electronic devices, batteries, fuel cells, catalytic converters, textiles and in chemical engineering and biotechnology. There is still a lot we do not know about how these small particles operate or will come to affect us and the environment in the long term.</div> <div><br /></div> <div><span><img src="/SiteCollectionImages/Institutioner/F/Divisions/Chemical%20Physics/Staff/clangham2.jpg" class="chalmersPosition-FloatRight" width="125" height="162" alt="" style="margin:5px" /></span>“Nanotechnology is developing fast in the world, but so far the research into nanosafety is not happening at the same pace. We therefore need to get a much better grasp of the risks and what distinguishes a hazardous nanoparticle from a non-hazardous one,” says Langhammer, Associate Professor, Department of Physics, Chalmers.</div> <div>“Our work indicates that not everything is what it seems – it’s the details that are crucial. To understand if and why nanoparticles are hazardous to humans, animals or nature, we also need to look at them individually.

The phenomenon of recorded lectures, nowadays also made freely available on the internet, started in California already in 1984. The local networking events around the world are called TEDx. TEDx Göteborg has been around since 2009.</div> <div> </div> <div>The theme for TedX Göteborg on 23 October is &quot;Brave New World&quot;. Tonight's host is the entrepreneur and venture capitalist Johan Staël von Holstein. Göran Johansson is in good company and shares the stage with Sveriges Television's CEO Hanna Stjärne, psychologist Katarina Blom, social entrepreneur Carolina Jonnor, psychologists Tyler Talib Fisher and Shubhaa Fisher, poet and activist Agnes Török, the company Techon Creative's founder and CEO Joel Rozada, as well as the psychologist and economist Per Espen Stoknes. There will also be performances of the yoga acrobats Tobias Strollo and Gabriella Bergbäck from Acro Yogis, and the dancer Mia Hellberg.</div> <div>From Chalmers, Asgeir Sigurjónsson, Shea Hagy and David Martinez also participate with their company EarthLab, which is a so-called sustainable development studio. The trio all holds a degree from the Master's Program &quot;Design for Sustainable Development&quot; at Chalmers.</div> <div> </div> <div>The title of Göran Johansson's lecture is &quot;The Conundrum of Quantum Computers&quot;. He will talk about the next quantum revolution, and how quantum computers in the future can change our way of learning new things about the world.</div> <div>&quot;I will talk about why I want to build a quantum computer. It will be recorded at Clarion Hotel Post in Gothenburg on 23 October&quot;, says Göran Johansson.</div> <div> </div> <h5 class="chalmersElement-H5">Is it open to an audience?</h5> <div>&quot;Yes, and I think someone mentioned that people from Chalmers have a discount.&quot;</div> <div> </div> <div>Göran Johansson is the second researcher from MC2, who is admitted to the Ted arena. Previously, the department head Mikael Fogelström, professor of theoretical physics, has spoken on two occasions. In November 2013 he spoke under the heading &quot;Graphene Science&quot;; a lecture that currently has over 300,000 views on Youtube. In October 2014, he spoke again, now under the heading &quot;Graphene, from a layer of atoms to applications&quot;, a lecture with over 86,000 views. The impact can thus be enormous.</div> <div> </div> <div>Text and photo: Michael Nystås</div> <div> </div> <div><a href="">Read more about Göran Johansson's Tedtalk</a> &gt;&gt;&gt;</div> <div> </div> <div><strong>Read more about the other speakers at TedX Göteborg &gt;&gt;&gt;</strong></div> <div><a href=""></a></div> <div> </div> <div><strong>Watch Mikael Fogelström's two Ted lectures &gt;&gt;&gt;</strong></div> <div><a href="">Graphene Science</a></div> <div><a href="">Graphene, from a layer of atoms to applications</a></div> <div> </div> <div><a href="/sv/forskning/chalmers-ted/Sidor/default.aspx">See other Chalmers researchers at Ted</a> &gt;&gt;&gt;</div> <div> </div>Tue, 10 Oct 2017 11:00:00 +0200
