This is going to be investigated by a group of researchers from Chalmers University of Technology in a five-year project. Their research is working toward a scientific breakthrough in the field of optical communication, for which they now have been granted SEK 30.7 million from the Knut and Alice Wallenberg Foundation.</b></p>​<span style="background-color:initial">The backbone of the Internet consists of hundreds of thousands of kilometers of optical fiber, in which enormous amounts of data are transferred around the globe. The demand for data seems to be insatiable and new applications connected to virtual reality (VR), big data, and Internet of things (IoT) are continuously adding to this. While the demand is increasing, the transmission capacity of optical fibers is limited. Moreover, installing and maintaining new fibers is costly and time-consuming. </span><div><br /><span style="background-color:initial"></span><div>“We claim that the optical fibers are vastly underutilized today”, says Professor Henk Wymeersch, leader of the research team. “Our goal is to quantify and demonstrate the fundamental limits of fiber-optical communications. We will address a number of scientific questions ranging from fundamental theory and modeling to component design and integration.”</div> <div><br /></div> <div><strong>Coordination is key</strong></div> <div>In the design of the current transmission schemes, coupling among the physical dimensions of the optical transmission – notably polarization, space, and frequency – is not taken into consideration when transmitting data. Current approaches rely on accessing the physical dimensions separately, while a joint design would allow for more data to be sent over the same physical dimensions. </div> <div><br /></div> <div>Henk Wymeersch describes this using an analogy with cars driving on multiple lanes:</div> <div><br /></div> <div>“If the cars are not coordinated at all, traffic jams and accidents inevitably will occur, that will slow down the traffic and delay everybody in reaching their destination. Similarly, the traffic flow in optical fibers is optimal when the transferred data is coordinated and adjusted across all physical dimensions.”</div> <div><br /></div> <div>“Comparatively little research has previously been conducted in the field of coordinated transmission in fiber optical communication”, Henk Wymeersch says. “The focus has been on the nonlinear high-power regime, while the linear coordinated regime has come back to the forefront, due to recent technological advances, including multi-mode fibers and optical frequency combs. These have made it possible to now move into this direction.” </div> <div><br /></div> <div>The granted money from the Knut and Alice Wallenberg Foundation will be used to obtain the necessary equipment for the experimental part of the project, and to extend the research team, currently consisting of six Chalmers researchers, with about six additional researchers. Collaboration with industry will also play an important role in the project.</div> <div><br /></div> <div><strong>Lower costs and higher capacity</strong></div> <div>Not only will this project lead to new and fundamental understanding of transmission over optical fibers, there will be a major cost reduction for society if the present fiber optic links can be utilized more effectively. The knowledge gained in this project can also be transferred to other applications, for example spectroscopy and fiber imaging. Moreover, the work has impact in wireless communications as well, as wireless and optical communications converge. </div> <div><br /></div> <div>“Quantifying and demonstrating the fundamental limits of fiber-optical communications would imply a new era in this field. If we succeed in this, our scientific results will change how current and future fiber-optical communication systems are used and designed”, Henk Wymeersch concludes. </div> <div><br /></div> <div>The looming “capacity crunch” on the Internet would thus be overcome, or at least postponed.</div> <div><br /></div> <div>Text: Yvonne Jonsson</div> <div>Photo: Johan Bodell</div> <div><br /></div> <div><div><strong>About the project</strong></div> <div>Title: Unlocking the full-dimensional fiber capacity</div> <div>Research team:</div> <div><a href="/sv/personal/Sidor/henk-wymeersch.aspx">Henk Wymeersch​</a>, Professor at the department of Electrical Engineering, Chalmers</div> <div><a href="/en/staff/Pages/erik-agrell.aspx">Erik Agrell</a>, Professor at the department of Electrical Engineering, Chalmers</div> <div><a href="/en/staff/Pages/Peter-Andrekson.aspx">Peter Andrekson</a>, Professor at the department of Microtechnology and Nanoscience, Chalmers</div> <div><a href="/en/Staff/Pages/Magnus-Karlsson.aspx">Magnus Karlsson</a>, Professor at the department of Microtechnology and Nanoscience, Chalmers</div> <div><a href="/en/staff/Pages/jochen-schroeder.aspx">Jochen Schröder</a>, Senior researcher at the department of Microtechnology and Nanoscience, Chalmers</div> <div><a href="/en/staff/Pages/Victor-Torres-Company.aspx">Victor Torres Company​</a>, Associate Professor at the Department of Microtechnology and Nanoscience, Chalmers</div> <div>Grant: SEK 30.7 million over five years</div> <div><br /></div> <div><strong><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about the Knut and Alice Wallenberg Foundation​</a></strong></div> <div>The Knut and Alice Wallenberg Foundation is Sweden's largest private financier of research.

A new research project at the Department of Computer Science and Engineering will investigate how to find and fix similar hardware bugs in the future, funded by a grant from Intel.</b></p><img src="/SiteCollectionImages/Institutioner/DoIT/Profile%20pictures/ST/Carl-Seger.jpg" class="chalmersPosition-FloatRight" alt="Professor Carl-Johan Seger" style="margin-bottom:20px;margin-left:20px" /> <p>“Virtually all modern, high performing processors in the world have these flaws, even your laptop or mobile phone. But the biggest problem is that it affects virtualization machines, for example, cloud services like Amazon Web Services. This means as a customer you might be able to read other customers’ data since you are sharing the same hardware.” says professor Carl-Johan Seger, who’s running the research project together with professor Alejandro Russo, at the Department of Computer Science and Engineering.</p> <p>The security flaws, named Meltdown and Spectre, allow programs to access sensitive data which is currently processed on the computer and stored in the temporary memory, the cache. In Spectre’s case, this is due to processors using speculative execution which creates a side-channel through which private information can be extracted. While an attacker can’t directly read the cache, it is possible to measure the timing of the cache to extract its content.</p> <p>“It’s almost like you are chasing a car. You lose sight of it and come to a parking lot and all the cars are parked. Which one is the car you were chasing? What you do is, you go around and check which car has a warm hood. Then you can determine that was the car, even if you didn’t see it park there” Carl-Johan Seger explains. </p> <p>There is no evidence of the flaws being used by hackers, but since the flaws have become public the risk for attacks increase.</p> <p><br /></p> <h5 class="chalmersElement-H5"> Combining techniques to fight future bugs </h5> <p>While processor and operative system manufacturers have released software patches to combat the flaws this does not fix the entire problem.</p> <p>“The hardware would most certainly need to be modified. That’s partly why this is so painful for the manufacturers. If you just patch the software it will most likely lead to a performance decrease. But what’s even more scary for most processor designers is, what if there is another bug, we haven’t found?” says Carl-Johan Seger.</p> <p>This is what the new research project, called Securing Multi-Cycle Hardware Architectures, will investigate.</p> <p>“Alejandro Russo and I have two pieces to this puzzle. He has a technique to look at a very big system and roughly identifying the problem area in a hardware component. My technology, symbolic simulation, allows you to analyze small pieces of hardware very accurately. This is a technology already used by Intel. Our research proposal is to combine our two techniques to find and help fix similar hardware bugs.”</p> <p><br /></p> <h5 class="chalmersElement-H5"> Funding for a three-year post-doc </h5> <p>The grant from Intel Corporate Research Council consists of 100 000 USD yearly and will be used to fund a post-doc that will work on the project together with Carl-Johan Seger and Alejandro Russo. The project was one of five in Europe to be funded out of over fifty proposals.</p> <p>“This is an interesting and challenging problem. The idea is not to fix these specific bugs, but rather to find a technique to identify where there might be problems with the hardware, and what those problems are. At least that’s what we promised to do. We’ll see what we succeed in.” Carl-Johan Seger concludes.</p> <p><br /></p> <h5 class="chalmersElement-H5">Contact</h5> <p><strong>Carl-Johan Seger</strong>, Research professor, Functional Programming division, Computer Science and Engineering</p> <p><a href=""></a>, +46 709 49 23 55, +46 31 772 64 19</p> <p><br /><strong>Alejandro Russo</strong>, Professor, Information Security division, Department of Computer Science and Engineering</p> <p><a href=""></a>, +46 31 772 61 56</p> <p><br /></p>Wed, 26 Sep 2018 13:00:00 +0200 collaboration in visualisation<p><b>​Visualization Research Gothenburg (VisRes) and Visual Arena have signed a collaboration agreement to join efforts in stimulating and strengthening development within, and through, visualisation.</b></p><div>​ <br /></div> <div><div>&quot;The goal of the collaboration is to form an open and neutral platform for academy, industry and society, which will promote and facilitate work within visualisation,&quot; says Monica Billger, academic leader and director of VisRes.</div> <div> </div> <div>Anyone who use, research or develop in visualisation, and those who seek inspiration and information about how to benefit from visualisation, are welcome to take part of the collaboration platform.

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 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.

In recent years researchers have developed artificial speciality materials – known as optomechanical metamaterials – which overcome the limitations inherent in natural materials in order to control the properties of light with a high degree of precision. For example, what are termed optical switches are used to change the colour or intensity of light. In internet traffic these switches can be switched on and off up to 100 billion times in a single second. But beyond that, the speed cannot be increased any further.

The conclusion she reached is that it is necessary to choose a different route to circumvent the speed limits: instead of controlling an entire surface at once, the interaction with light can be controlled more efficiently by manipulating one particle at a time. Another way of solving the problem is to allow the speciality material to remain in constant motion at a constant speed and to measure the variations from this movement.</div> <div> </div> <div>But Viaene and her supervisor, Associate Professor Philippe Tassin, say that the speed limit does not pose a problem for all applications.

With a unique software in their car, the team hopes to wipe the floor with their competitors.</b></p><div>Already available was a whole lab dedicated to the development of self-driving vehicles, a proprietary software platform, and a ready-made electric racing car from last year's Formula Student competition.</div> <div><br />&quot;From there, it was quite a small step, to start a student team to rebuild the car for self-driving and compete in the race class for driverless cars,&quot; says the initiator and supervisor Ola Benderius, assistant professor at the Vehicle Engineering and Autonomous Systems Division.<br /><br /></div> <div>Since last autumn, twelve students from five different master programs have worked to make the car self-driving as part of their master’s thesis.</div> <div><br />&quot;It's extremely fun and educational. It's a brand-new project and we have had a lot of freedom to achieve our goals,&quot; says team manager Emil Rylén, who studies Automotive Engineering.</div> <div> </div> <h3 class="chalmersElement-H3">A dedicated and multifaceted team</h3> <div>The team is divided into three groups, who work with each of the three main elements of self-driving: to perceive and interpret the surroundings, driving planning and control, and mechanical and electronic hardware to execute the control signals. Two of the team members were also in the team that built the car last year.</div> <div><br />&quot;We couldn’t have done it without them. They know and understand how the car works,&quot; says Rylén.</div> <div>He describes the team as a very mixed group, both in terms of nationality, education and skills.</div> <div><br />&quot;Everyone is really dedicated. You definitely do not have to be a racing fan, but rather a technology fan and someone interested in cutting-edge technology.&quot;</div> <div> </div> <h3 class="chalmersElement-H3">Equipment for half a million SEK</h3> <div>To make the car self-driving, they have equipped the car with sensors like GPS, laser radar, dual-lens camera for deep vision, computers, and extra electronics and mechanisms to actuate the brakes, wheel, and accelerator. In total, the equipment cost about half a million SEK, but much of it will be reusable in coming years.</div> <div><br />Financing is already ready for another three years. Interest among the students is very high, as is the industry's interest in recruiting those who participated in the team. Ola Benderius and his two supervisor colleagues – Christian Berger and Björnborg Nguyen – are already gathering next year's team.</div> <div><br />It is also advantageous for the Chalmers lab for self-driving vehicles, <a href="/en/researchinfrastructure/revere/Pages/default.aspx" target="_blank">Revere</a>, to have a team in Formula Student Driverless.</div> <div><br />&quot;We get a chance to showcase Reveres’ abilities and skills, and the team attracts really good students. Hopefully, some of them hope to stay on as PhD students. In addition, the team is developing stuff that we can use in research,&quot; says Benderius.</div> <h3 class="chalmersElement-H3">Tests and competition in sight</h3> <div>In addition to the team being able to use Reveres’ premises, vehicles and skills, they also get time on the test track Astazero. At the moment, they can drive the racing car using a handheld remote control, but there is still a few weeks work before they can go over to self-driving tests.</div> <div><br />&quot;It will be very fun to test and go to the competition. Then we can reap the benefits of all the work we put down during the year,&quot; says Rylén.</div> <div><br />While the other teams qualifying for the competition all chose the same well-established but somewhat obsolete software, the Chalmers team uses Chalmers’ proprietary software platform for driverless vehicles, OpenDLV.</div> <div><br />“It makes us unique. A stable software is really important to succeed in the competition, and with experience from research, we know how to design it,&quot; says Benderius.</div> <h3 class="chalmersElement-H3">About the Formula Student Driverless competition</h3> <div>The competition will take place 6–12 August in Hockenheim, Germany, and includes a number of different challenges: braking, acceleration, skidpad testing and a track drive. The team will also have to present and explain their software and hardware design, as well as a business model.

We will both have prominent researchers from around the world, who will present new research findings, and also large and small companies from industry. To me it is extremely honorable to have a leading role in this conference, not many people get the chance&quot;, says Ivica Crnkovic.<br /><br /><strong>Double anniversary</strong><br />This year's edition is also special, as two anniversaries will be celebrated. It’s the 40th edition of ICSE, and Software Engineering as a discipline celebrates 50 years. The discipline was introduced at the famous NATO Software Engineering Conference 1968 in Garmisch, Germany. For the anniversary, several high-profile keynote speakers have been booked and one of them is Margaret Hamilton – a legend in Software Engineering who developed the software that governed and controlled the Apollo program’s spacecraft.<br /><br />&quot;It's very exciting that Margaret Hamilton is coming! She was the first in the world to develop the software required for a rocket to navigate and land on the moon, so she's really a pioneer. She was very enthusiastic when we contacted her, and with her experience she will contribute with truly interesting insights and knowledge”, says Ivica Crnkovic.<br /></div> <div><br /></div> <div><strong>Record breaking number of participants</strong><br />This year, the conference is the largest in its 40-year history. More than 1700 participants from all over the world registered. International researchers are attracted to Sweden, partly thanks to our strong cooperation between industry and academia which makes us a model in many countries.<br /><br />&quot;The ICSE is a unique conference within its field and now that it is held for the first time in Scandinavia, it is a great opportunity for Scandinavian and Swedish industry to showcase and establish contacts. The ICSE can be resembled as the Olympics of our discipline, so it's a very big event!”, says Ivica Crnkovic.<br /><br />The conference was held between 27 May and 2 June and offered 30 workshops, six co-located events, and three days of the main conference with several prominent speakers and more than 500 presentations.<br /><br /><br /><a href="/en/areas-of-advance/ict/news/Pages/Follow-the-Software-Conference-on-live-stream.aspx">Some of the content is available on video &gt;</a><br /><br /></div> <div><br /></div> <div><br /></div> <div>Conference website: <a href=""></a>.<br /><a href="" target="_blank">Register for this year's event in Software Engineering here &gt;</a><br /><br /><br /><br /><br />Software engineering is about developing software systems, or program intensive systems.
