Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.
Limited scalability and the high sensitivity of qubits as building blocks for the quantum computer are still in the way of the ‘super computer’s’ big breakthrough. Researchers of the University of Twente, together with colleagues from Austria, Switzerland and the Netherlands may have found a promising solution to address these challenges. They have been awarded a 3.1 million euro financial contribution from the EU’s Future and Emerging Technologies (FET) programme.
Mit einem Beitrag über ein rotierendes System von Satellitengalaxien hat der Basler Physiker Dr. Oliver Müller den KlarText-Preis gewonnen. Die Klaus Tschira Stiftung zeichnet ihn damit für seine herausragende Wissenschaftskommunikation aus. Mehr Informationen sind auf der Seite der "Swiss Society for Astrophysics and Astronomy" zu finden.
Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report in the scientific journal Nature Materials.
The electron spin of individual electrons in quantum dots could serve as the smallest information unit of a quantum computer. Scientists from the Universities of Oxford, Basel and Lancaster have developed an algorithm that can be used to measure quantum dots automatically. Writing in the Nature-family journal npj Quantum Information, they describe how they can speed up this hugely time-consuming process by a factor of four with the help of machine learning. Their approach to the automatic measurement and control of qubits therefore represents a key step toward their large-scale application.
Christoph Bruder has been awarded this honor for his work on quantum theory of many-body coherent phenomena in
mesoscopic electron systems, cold atoms, and nanomechanical systems by the Division of Condensed Matter Physics (DCMP).
Am nächsten Montag 16. September 2019 heissen wir die neuen Physikstudierenden um 13:15 Uhr im neuen Hörsaal 1 der Physik, Eingang St. Johanns-Ring 25, willkommen. Zum gegenseitigen Kennenlernen gibt es im Anschluss um 15 Uhr einen Apéro in der SVI Mensa im 3ten Stock des Departements Physik. Wir wünschen viel Erfolg!
In power electronics, semiconductors are based on the element silicon – but the energy efficiency of silicon carbide would be much higher. Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what exactly is preventing the use of this combination of silicon and carbon in the scientific journal Applied Physics Letters.
We congratulate our apprentice Noah Simon Graber for having successfully passed his final exams of his Polymechanics apprenticeship.
Out of overall 31 Polymechanics apprentices in the Basel area, his ranking was among the top 6 with an excellent mark of 5.3.
On Wednesday, June 10th 2019, a group of female physicists from various different research groups of the Department of Physics at the University of Basel set out on a journey to Beckenried, NW, at the shore of Lake Lucerne, to go on their first Women in Physics networking hike. The goal of this event, which is also a part of the NCCR QSIT equal opportunities program, is to get to know each other, talk about both physics-related and -unrelated topics in a relaxed environment, and build up a sense of community among the female members of the department. After taking the cable car to Klewenalp, which offered amazing views of Lake Lucerne and the surrounding mountains, our path led us uphill to the SAC hut Brisenhaus, and from there in a big loop through meadows and forests back to Klewenalp. There, everyone was happy to get their well-deserved coffee and enjoy the sun until the cable car took us back down and we started our way home back to Basel.
