Master Student Märta Tschudin on her graduate student experience at the University of Basel.
A new technique makes it possible to obtain an individual fingerprint of the current-carrying edge states occurring in novel materials such as topological insulators or 2D materials. Physicists of the University of Basel present the new method together with American scientists in “Nature Communications.”
Physicists at the University of Basel are working on using the spin of an electron confined in a semiconductor nanostructure as a unit of information for future quantum computers. For the first time, they have now been able to experimentally demonstrate a mechanism of electron spin relaxation that was predicted 15 years ago. The scientists also succeeded in keeping the direction of the electron spin fixed for almost a minute – a new record. The results of the collaboration with researchers from Japan, Slovakia and the US have been published in Nature Communications.
Ambizione grants are aimed at young researchers who wish to conduct, manage and lead an independent project at a Swiss higher education institution. The scheme supports young researchers both from Switzerland and abroad. Scientists holding non-professorial academic positions at higher education institutions are also eligible to submit an application. [Source: SNF]
For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure, in which a quantum system is integrated into a nanoscale mechanical oscillator in form of a diamond cantilever. Nature Physics has published the study that was conducted at the University of Basel and the Swiss Nanoscience Institute.
Synchronization is ubiquitous in our everyday life. We experience it for instance when getting jetlagged after a long trip; there, the underlying mechanism is the synchronization of our circadian rhythm to the day-night cycle. Physicists in Basel have addressed a major difficulty that arises when trying to understand this phenomenon in a quantum setting. They have identified the minimal quantum resource that can be synchronized to an external periodic signal. Their system can be readily implemented in the laboratory and provides the ideal platform for studying complex large networks of quantum units. The results have been published in Physical Review Letters and featured as a viewpoint in Physics. We discuss the relation between quantum synchronization and entanglement in another Physical Review Letters.
Quantencomputer besitzen eine Aura des Mystischen, nicht Verstehbaren. Das Spiel «Hello Quantum» soll das ändern. Der Quantenphysiker James Wootton von der Universität Basel hat diese App gemeinsam mit IBM entwickelt.
Dr. Daniel Riedel, Postdoc in the team of Professor Richard Warburton and PhD student in the SNI’s PhD School until December 2017, received the Swiss Nanotechnology PhD Prize 2018 sponsored by the Hightech Zentrum Aargau. He received the award for his publication in Physical Review X about the improvement of the quality of photons generated by a quantum system.
