Researchers at IST Austria have built compact photon directional devices. Their micrometer-scale, nonmagnetic devices route microwave photons and can shield qubits from harmful noise.
Qubits, or quantum bits, are the key building blocks that lie at the heart of every quantum computer. In order to perform a computation, signals need to be directed to and from qubits. At the same time, these qubits are extremely sensitive to interference from their environment, and need to be shielded from unwanted signals, in particular from magnetic fields. It is thus a serious problem that the devices built to shield qubits from unwanted signals, known as nonreciprocal devices, are themselves producing magnetic fields. Moreover, they are several centimeters in size, which is problematic, given that a large number of such elements is required in each quantum processor. Now, scientists at the Institute of Science and Technology Austria (IST Austria), simultaneously with competing groups in Switzerland and the United States, have decreased the size of nonreciprocal devices by two orders of magnitude. Their device, whose function they compare to that of a traffic roundabout for photons, is only about a tenth of a millimeter in size, and—maybe even more importantly—it is not magnetic.
Sebastian Zeidler holds a PhD in art theory and art criticism from Columbia University in New York, NY, United States, and most recently held the position of associate professor in the History of Modern Art at Yale University in New Haven, CT, United States. His monograph, “Form as Revolt: Carl Einstein and the Ground of Modern Art,” was published in 2016. As a NOMIS fellow, he is working on a research project on Edmund Husserl’s image theory and the art of Henri Matisse, investigating, for example, the way in which both the philosopher and the artist consider the possibility of the world’s appearance in its full splendor to depend on the individual’s removal or detachment from that world.
Ingrid Vendrell-Ferran earned a PhD in philosophy from the Free University in Berlin, Germany, in 2007 and qualified as a professor in 2017 with a book on the cognitive forms of literature. She is the author of the monographs “Die Emotionen: Gefühle in der realistischen Phänomenologie” (“Emotions: Feelings in Realistic Phenomenology”), and “Die Vielfalt der Erkenntnis: Eine Analyse des kognitiven Werts der Literatur” (“The Diversity of Knowledge: An Analysis of the Cognitive Value of Literature”). As a NOMIS fellow, she is applying the results of her second book on empathy in literature to the medium of film with a project titled “Imaginative Participation and Empathic Recognition in Documentary Film.”
Swiss newspaper Tages Anzeiger published an article about NOMIS Distinguished Scientist awardee Karl Deisseroth. Titled “The cerebral man” (translated from the original German “Der Kopfmensch”), the article details Deisseroth’s significant contributions to the study of the human brain. Deisseroth developed optogenetics, a technique that uses light to manipulate cells in the brain, and CLARITY, a technique that enables researchers to see the protein and nucleic acid structures inside the intact brain.
— Recognizing not only scientific excellence, but also celebrating researchers who push for unconventional paths and show exceptional engagement in insight-driven research and collaboration, the NOMIS Distinguished Scientist Award 2017 was presented to Karl Deisseroth, Tony Wyss-Coray, and Svante Pääbo on Thursday, Oct. 19, 2017 at the Gottlieb-Duttweiler-Institute (GDI) in Rüschlikon, Switzerland. Founded on the principle that the facility should be a place for reflection on socially significant ideas, the GDI served as the perfect venue.
With over 100 guests, among them top scientists and scholars, representatives of world-renowned research institutes, and a number of research funders from both Switzerland and Germany, the ceremony was a culmination of acknowledging not only the relevance of basic research but also the importance of a mutualistic relationship between researchers and research funders.
The award ceremony was followed by a panel discussion with Nobel Laureate and president of the Salk Institute, Elizabeth Blackburn, and the three awardees. The discussion addressed topics such as how scientists protect creativity and innate curiosity when confronted with the expectation that they must produce tangible results, how they approach risk in research, and the public perception of their science. Concluding with a networking dinner, the event showed to be a meaningful opportunity for an informed, lively and engaging exchange of ideas.
Prior to the award ceremony, the awardees presented their work at a public lecture series at ETH Zurich on Wednesday, Oct. 18 and at the University of Zurich on Thursday, Oct. 19.
Deisseroth’s lecture, “Illuminating the brain,” shed light on his groundbreaking work in neuroscience. Deisseroth is widely recognized for developing and implementing an approach to biology called optogenetics, a technique that involves the use of light to control cells in living tissue. The NOMIS Distinguished Scientist Award enables Deisseroth and his team to implement the project ‘”Circuit States: Discovering the Causal Principles Underlying Brain-wide Dynamics,” which will adapt and combine new technologies developed in Deisseroth’s lab. The awardee hopes to gain insights into the interacting functions of neurons across multiple brain areas.
A founder of paleogenetics, Svante Pääbo became best known for his pathbreaking research on the Neandertal genome. Pääbo’s lecture, “A neandertal view of human uniqueness,” described his quest to learn more about the genetic differences and functional consequences that occurred at the split between the modern human and their archaic human ancestors about half a million years ago. The NOMIS award enables Pääbo’s research on the genetic underpinnings of the human condition and thus potentially provides an additional avenue to study diseases and other conditions that affect uniquely human traits.
Tony Wyss-Coray’s lecture, “Blood proteins regulating brain function and aging,” described his investigation into the role of aging on neurodegeneration in general and Alzheimer’s disease in particular. His research has shown that the administration of young blood into old organisms has functional consequences, appearing to “rejuvenate” an aged brain. With the support of the NOMIS Distinguished Scientist Award, Wyss-Coray and his team are setting out on the quest to identify the key proteins and genes that are at the core of this rejuvenating effect, which could produce vital new insights into biological aging.
Swiss newspaper Die Neue Zürcher Zeitung (NZZ) has published an interview with NOMIS Distinguished Scientist Svante Pääbo about his work in the field of paleogenetics, and more specifically, about the relevance of Neandertal genes in humans today. Although Europeans carry at most 2 percent Neandertal-derived gene variants, certain diseases such as type 2 diabetes — which today is a global epidemic — have been traced back to Neandertal DNA.
The interview was originally published in German under the title, “Was der Neandertaler mit heutigen Krankheiten zu tun hat.”
