Draft:Dominik Zumbühl

Dominik Zumbühl is a Swiss experimental physicist and professor at the University of Basel. He is known for his contributions to quantum coherence, spin physics, and semiconductor quantum dots.

He obtained a physics diploma from ETH Zürich in 1998, followed by a Master of Science degree from Stanford University in 2000. He received his PhD from Harvard University in 2004, focusing on quantum coherence and spin in semiconductor quantum dots. Following his doctoral studies, Zumbühl completed a two-year postdoctoral fellowship at the Massachusetts Institute of Technology (MIT) before establishing his own research group at the University of Basel in 2006, where he set up a low temperature quantum transport laboratory and research group.

Zumbühl was awarded a starting grant in the first European Research Council (ERC) call in 2008. He was promoted to associate professor in 2012 and then to full professor in 2023 at the University of Basel. Zumbühl served as the Department Chair from 2015 to 2019 and has been the director of the NCCR SPIN (Swiss National Program on Quantum Computing with Si and Ge spins) since 2021.

In 2023, Zumbühl was elected as a fellow of the American Physical Society (APS) "for quantum transport experiments in semiconductor nanostructures at low temperatures studying coherence, spins, and spin-orbit coupling including developing and deploying laboratory instruments".

Dominik Zumbühl co-founded Basel Precision Instruments GmbH (BASPI) in 2018. BASPI is a provider of ultra-low noise laboratory electronics and microwave filters and thermalizers. This includes ultra-low noise and ultra-stable current and voltage preamplifiers, ultra-precise voltage sources with microvolt resolution, and cryogenic filter and thermalizer solutions.
