But how can healthcare managers handle these management innovations in a way that results not only in pretty words but in actual improvements? Christian Colldén is a physician and healthcare manager who in his doctoral thesis at Chalmers has studied how management innovations can be understood and translated into a local context to improve the quality and efficiency of care.</b></p><h3 class="chalmersElement-H3">​What challenges do you focus on in your research?</h3> <div>&quot;All those who have tried to improve healthcare systems have probably realised that it is a very challenging undertaking. Demands often come from many directions, strong professions with diverse opinions and views are to be brought on the same track, and processes are seldom straight and separate. Management innovations are often presented as comprehensive and consummate concepts, which will solve the problems of healthcare, but earlier research have shown that they often do not deliver the promised improvements. Healthcare professionals also often meet management innovations with skepsis. On the other hand, there are examples of management innovations being positively received and resulting in improved quality and efficiency. The challenge that I focus on is how managers can improve the complex healthcare systems that they act in, and how management innovations can become useful tools in that work.&quot;</div> <h3 class="chalmersElement-H3">How do you address the problem with your research?</h3> <div>&quot;I have been inspired by action research, which implies that I have tried to achieve improvements in my own context at the same time as I have collected data to analyse what me and my colleagues have done in practice. I have worked in psychiatry within the Sahlgrenska University Hospital and, hopefully, the projects have created better conditions for innovativeness quality improvements. At the general level I try to contribute to a better understanding of how to use management innovations so that they are positively received by different actors in healthcare and create improvements. That general knowledge can be used in education for managers and staff who support managers in development and improvement work.&quot;</div> <h3 class="chalmersElement-H3">What are the main findings?</h3> <div>&quot;Different actors in healthcare, like nurses, physicians, politicians, and care developers, have different views on what quality in care means, how care should be provided in a high-quality fashion, and how improvements can be achieved. Thus, they can be seen to rely on different logics. In the same way, different management innovations rely on one or several logics. By mapping underlying logics, healthcare managers can create an appreciation for the complex system and match concepts with the context.&quot;</div> <div> </div> <div>&quot;Next, managers should translate rather than implement management innovations, which implies that one should view them not as fixed concepts but as mouldable ideas. A concrete example is Value-based Healthcare, which can be seen as relying on both a logic of standardisation (of care processes for defined patient groups) and a logic of goal orientation (that if we measure outcomes and costs, the manager need not decide how the result is to be achieved). Based on the understanding of what is needed and/or will be best received in the specific organisation, different aspects of management innovations can be emphasized to make a positive impact and drive change. Management innovations in themselves seldom solve the problems but they can be used as strategic tools and sources of inspiration.&quot;</div> <h3 class="chalmersElement-H3">What do you hope your research will lead to? </h3> <div>&quot;Unfortunately, there are no shortcuts to improvements in healthcare, but research can provide some advise on how to take on the task. For example, appreciation of the surrounding system and its components – especially what drives the individuals that you want to involve in new ways of working. I hope that managers and others who drive development in healthcare can adopt that approach and that it is also highlighted in management training programmes, by internal support functions for care development, and by external consultants. If this view gains impact, I believe that frustration can be turned into constructiveness and real improvements.&quot;</div> <div> </div> <div><br /><br /></div> <div> </div> <div><em>Text compilation: Daniel Karlsson</em><br /></div> <div> </div> <div><br /></div> <div>Read the thesis <a href="" target="_blank">&quot;Managing management innovations: Contextual complexity and the pursuit of improvements in healthcare&quot;</a></div> <div> </div> <div>The author will defend the thesis on 7 October 2022 at 13.15, see link on the <a href="" target="_blank">thesis’ page</a><br /></div> <div> </div> <div><br /></div> <div> More about <a href="/en/Staff/Pages/christian-ohrn.aspx">Christian Colldén</a></div> <div> </div>Thu, 29 Sep 2022 09:00:00 +0200 from Chalmers heading for Silicon Valley<p><b>​Every year the Swedish innovation agency Vinnova selects research projects for the exclusive incubator program Reach with focus on technology relevant for the ecosystem in Silicon Valley and with the potential to be commercialised.

In addition to creating previously known states, the researchers are the first ever to demonstrate the long-sought cubic phase state. The breakthrough is an important step towards efficient error correction in quantum computers.</b></p>​“We have shown that our technology is on par with the best in the world,” says Simone Gasparinetti, who is head of a research group in experimental quantum physics at Chalmers and one of the study’s senior authors.<br /><div><br /></div> <div>Just as a conventional computer is based on bits that can take the value 0 or 1, the most common method of building a quantum computer uses a similar approach. Quantum mechanical systems with two different quantum states, known as quantum bits (qubits), are used as building blocks. One of the quantum states is assigned the value 0 and the other the value 1. However, on account of the quantum mechanical state of superposition, qubits can assume both states 0 and 1 simultaneously, allowing a quantum computer to process huge volumes of data with the possibility of solving problems far beyond the reach of today’s supercomputers. </div> <h2 class="chalmersElement-H2">First time ever for cubic phase state</h2> <div>A major obstacle towards the realisation of a practically useful quantum computer is that the quantum systems used to encode the information are prone to noise and interference, which causes errors. Correcting these errors is a key challenge in the development of quantum computers. A promising approach is to replace qubits with resonators - quantum systems which, instead of having just two defined states, have a very large number of them. These states may be compared to a guitar string, which can vibrate in many different ways. The method is called continuous-variable quantum computing and makes it possible to encode the values 1 and 0 in several quantum mechanical states of a resonator. </div> <div><br /></div> <div>However, controlling the states of a resonator is a challenge with which quantum researchers all over the world are grappling. And the results from Chalmers provide a way of doing so. The technique developed at Chalmers allows researchers to generate virtually all previously demonstrated quantum states of light, such as for example Schrödinger's cat or Gottesman-Kitaev-Preskill (GKP)states, and the cubic phase state, a state previously described only in theory.</div> <div><br /></div> <div>“The cubic phase state is something that many quantum researchers have been trying to create in practice for twenty years. The fact that we have now managed to do this for the first time is a demonstration of how well our technique works, but the most important advance is that there are so many states of varying complexity and we have found a technique that can create any of them,” says Marina Kudra, a doctoral student at the Department of Microtechnology and Nanoscience and the study’s lead author.</div> <h2 class="chalmersElement-H2">Improvement in gate speed</h2> <div>The resonator is a three-dimensional superconducting cavity made of aluminium. Complex superpositions of photons trapped inside the resonator are generated by interaction with a secondary superconducting circuit.   The quantum mechanical properties of the photons are controlled by applying a set of electromagnetic pulses called gates. The researchers first succeeded in using an algorithm to optimise a specific sequence of simple displacement gates and complex SNAP-gates to generate the state of the photons. When the complex gates proved to be too long, the researchers found a way of making them shorter using optimum control methods to optimise the electromagnetic pulses.<br /></div> <div><br /></div> <div>“The drastic improvement in the speed of our SNAP gates allowed us to mitigate the effects of decoherence in our quantum controller, pushing this technology one step forward. We have shown that we have full control over our quantum mechanical system,” says Simone Gasparinetti.</div> <div><br /></div> <div>Or, to put it more poetically: </div> <div><br /></div> <div>“I captured light in a place where it thrives and shaped it in some truly beautiful forms,” says Marina Kudra.</div> <div><br /></div> <div>Achieving this result was also dependent on the high quality of the physical system (the aluminium resonator itself and the superconducting circuit.) Marina Kudra has previously shown how the aluminium cavity is created by first milling it, and then making it extremely clean by methods including heating it to 500 degrees Centigrade and washing it with acid and solvent. The electronics that apply the electromagnetic gates to the cavity were developed in collaboration with the Swedish company Intermodulation Products.</div> <div><br /></div> <h2 class="chalmersElement-H2">Research part of WACQT research programme</h2> <div>The research was conducted at Chalmers within the framework of the Wallenberg Centre for Quantum Technology (WACQT), a comprehensive research programme, the aim of which is to make Swedish research and industry leaders in quantum technology.

But it also calls out the shortcomings of sector-specific initiatives that are limited in their ability to deal with indirect impacts.</div> <div><br /></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">New import measures a major step forward​</span><br /></div> <div>“Sector specific initiatives to combat deforestation can be invaluable, and new measures to prohibit imports of commodities linked to deforestation in consumer markets, such as those under negotiation in the EU, UK and USA represent a major step forward from largely voluntary efforts to combat deforestation to date,'' said Dr. Toby Gardner of the Stockholm Environment Institute and Director of the supply chain transparency initiative, Trase.</div> <div><br /></div> <div>“But as our study shows, strengthening forest and land-use governance in producer countries has to be the ultimate goal of any policy response. Supply chain and demand-side measures must be designed in a way that also tackles the underlying and indirect ways in which agriculture is linked to deforestation. They need to drive improvements in sustainable rural development, otherwise we can expect to see deforestation rates remaining stubbornly high in many places,” Dr. Gardner added.</div> <div><br /></div></div> <div><span style="background-color:initial">The study’s findings point to the need for supply chain interventions to go beyond a focus on specific commodities and risk management, to help drive genuine partnerships between producer and consumer markets and governments. This needs to include strong incentive-based measures that make sustainable agriculture economically attractive, while disincentivising further conversion of native vegetation and supporting the most vulnerable smallholder farmers. The authors say this should include a stronger focus on domestic markets, often the biggest drivers of demand for many commodities, including beef, and a strengthening of partnerships between companies, governments and civil society in producer jurisdictions.</span></div> <div><br /></div> <div><span style="background-color:initial"> <h3 class="chalmersElement-H3">Several critical evidence gaps</h3> <div>Finally, the study highlights three critical gaps where a stronger evidence base is needed to better target efforts to reduce deforestation; </div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Profilbilder/Martin_Persson_2022.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br />“The first is that without a globally and temporally consistent data product on deforestation we cannot be confident about overall trends in conversion. The second is that except for oil palm and soy, we lack data on the coverage and expansion of specific commodities to know which are more important, with our understanding of global pasture and grazing lands being especially dire. The third is that we know comparatively very little indeed about tropical dry forests, and forests in Africa”, said Professor Martin Persson of Chalmers University of Technology. </div> <div><br /></div> <div>“What is most worrying, given the urgency of the crisis”, added Prof. Persson, “is that each of these evidence gaps pose significant barriers to our ability to drive down deforestation in the most effective way – by knowing where the problems are concentrated, and understanding the success of efforts to date”.</div> <div><br /></div> <div>Despite these knowledge gaps and remaining uncertainties, the study stresses that a step-change in efforts is urgently needed to effectively tackle and curb deforestation and conversion of other ecosystems and to foster sustainable rural development. The Glasgow Declaration on Forests recognised the importance of jointly addressing the crises of climate and biodiversity loss and set a new level of ambition for tackling deforestation and promoting sustainable agriculture. The authors of this new study say it is paramount that we begin to see individual countries and policymakers prioritise the realisation of this ambition.</div></span></div> <div><br /></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">More info about the research </span><br /><span style="background-color:initial"></span></div> <div><a href="">The research article Disentangling the numbers behind agriculture-driven tropical deforestation</a> was published in Science 377, 9 September 2022.

New research results at Chalmers University of Technology, Sweden, now give a deeper understanding of how the line width in the combs works, something that will, among other things, enable even more precise measurements in the future. And the discovery was made almost by coincidence.</b></p><div>​A ruler made of light. That is the simplified comparison that is commonly used to describe what a microcomb is. In short, the principle is based on a laser sending light that circulates inside a small cavity, a so-called microresonator. There, the light is divided into a variety of colours, or frequencies. The frequencies are precisely located, similar to the markings on a ruler.</div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>Today, virtually all optical measurements can be linked to light frequencies, and this gives the microcombs a plethora of different application areas – everything from calibrating instruments that measure signals at light-years distances, to identifying and keeping track of our health via the air that we exhale.</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">New insights on the frequency comb’s lines </h2> <div> </div> <div> &quot;Laser frequency combs have revolutionised research that relies on frequency metrology,&quot; says Victor Torres Company, professor at the Department of Microtechnology and Nanoscience, MC2, at Chalmers University of Technology.</div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>A key question when working with microcombs is how narrow the frequency comb lines are. The prevailing view until a few years ago was that the lines cannot be narrower than the input light from the laser. When researchers began to examine this more in depth, it was discovered that the lines located farther out from the laser are a little wider than the centrally located lines. Noise sources in the micro resonator were thought of as the reason for this.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>When Fuchuan Lei, researcher at MC2, tested these theories and ran the experiments with devices fabricated at the MC2 Nanofabrication Laboratory facilities, he discovered that some of the lines were in fact narrower than the light of the laser source itself. He traced all noise sources that can influence the linewidth or the purity of the lines, repeated the experiments and continued to receive the same result.</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">A new theory in place</h2> <div> </div> <div> &quot;We didn't understand why but based on these results we developed a theoretical model that explained what happened, did simulations, and confirmed via experiments that our model was correct”, says Victor Torres Company. “Earlier on it was not clear how the different noise mechanisms would affect the linewidth of the comb lines in the micro comb”.</div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>&quot;At first we thought something must be wrong, but once we had our theory in place everything was clear&quot;, says Fuchuan Lei.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>How narrow the markings are in a microcomb has great significance in how it can be used. A microcomb with narrowly placed markings allows for even more precise measurements, and that is why understanding why the lines are narrower is a key issue in the development of microcombs.  Victor Torres Company compares it to rulers made of different kinds of materials.</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">Possible to measure more precisely</h2> <div> </div> <div> “Imagine you would draw markers with some chalk versus if you would do it with a pencil.

It functions as a ruler made of light, where the markers set the frequency scale across a portion of the electromagnetic spectrum, from the ultraviolet to the mid infrared. The location of the markers can be linked to a known reference. This was achieved in the late 90s, and it signified a revolution in precision metrology – an achievement recognised by the Nobel Prize in Physics in 2005.</div> <div> </div> <div><br /></div> <div>A microcomb is a modern technology, alternative to mode-locked lasers, that can generate repetitive pulses of light at astonishing rates. They are generated by sending laser light to a tiny optical cavity called a microresonator. Thus, microcombs have two important attributes that make them extremely attractive for practical purposes: the frequency spacing between markers is very large (typically between 10 – 1,000 GHz), that is much higher than the spacing in mode-locked laser frequency combs, and they can be implemented with photonic integration technology. The compatibility with photonic integration brings benefits in terms of reduction of size, power consumption and the possibility to reach mass-market applications. The large spacing between teeth means that microcombs can be used for novel applications, such as light sources for fiber-optic communication systems or for the synthesis of pure microwave electromagnetic radiation.</div> <div><br /></div> <div>Text: Robert Karlsson and Mia Halleröd Palmgren</div> <div>Photo: Fuchuan Lei and Mia Halleröd Palmgren<br /></div> <div> </div> Mon, 05 Sep 2022 07:00:00 +0200 skier test their limits<p><b>The super skier Max Novak, who is probably the world's best roller skier and who during the summer has won great victories in both Sweden and Norway, visited Chalmers and tested in the physiology lab, which is located in a brand-new learning environment that will soon be inaugurated</b></p>​<span style="background-color:initial;font-size:14px">Novak was there to test the limit of how fast he can ski under controlling shapes.

Entrepreneurship and innovation is not necessarily sustainable by default – there is a large need for better tools and insightful reflections, to help shape more sustainable futures&quot;, says Karen Williams Middleton, Associate professor at the Department of Technology Management and Economics, and course examiner of the new summer school at Chalmers.<br /><br />The initiative is created within the ENHANCE alliance of technical universities and is a part of the Tracks courses at Chalmers. Before and after the intensive week in late August, the students carry out academic research in teams, with the aim of creating value in a sustainable manner for people around Europe, and the planet as a whole. <br /><br />&quot;The group of PhD and master students from our seven ENHANCE partner universities came with huge interest, engagement and challenging questions to Gothenburg for the in-person week. We designed the course to include several novel approaches: interviews with sustainable entrepreneurs; synthesis of individual interviews in a group format; lectures by researchers, institutional players, and entrepreneurs; student-led sessions including workshop facilitations by students; and field trips to exemplary initiatives in the Gothenburg region. This all aimed to familiarize the technical students with four main aspects relevant to sustainable entrepreneurship and innovation: systemic, value creation, collaboration/teamwork, and funding&quot;, says course leader, Yashar Mansoori, a post-doc working with ENHANCE at Chalmers.<br /><br />One of the students was Arpita Chari, PhD Student at the Department of Industrial and Materials Science at Chalmers:<br /><br />&quot;I applied to the course because I was interested in innovation and entrepreneurship when it comes to business strategies with respect to sustainability, especially the aftereffects of the covid pandemic. I also wanted to apply the skills garnered from the summer school to industrial level issues after I graduate from my PhD program.&quot;<br /><br />&quot;Considering that this was the first time the course is being run, I think it was very well designed and structured. The themes were relevant, and all the lectures and workshops were thoughtfully connected to the themes. I liked that there was one main academic lecture, one policy/legal lecture, one talk by a sustainability entrepreneur and then the student-led workshops each day.
