Dr. Stefan Filipp holds a position as Full Professor (Chair) in Physics at the TU Munich and as Director of the Walther-Meißner-Institute of the Bavarian Academy of Sciences and Humanities since May 2020. Before he has been working at IBM Research where he joined in 2014 at the Watson Research Center in New York, USA to work on superconducting circuit quantum computing. In September of 2015, Stefan moved to the IBM Research – Zurich Laboratory, where he then became technical leader of the superconducting qubit team focusing on quantum information processing with superconducting circuits.

Prior to joining IBM, Stefan was a member of the Quantum Device Lab of the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, from 2008 to 2014, where he worked on hybrid cavity QED, geometric phases, quantum optics and quantum information processing with superconducting circuits.

Stefan was awarded a PhD (with distinction) in Technical Physics from the Technical University of Vienna, Austria in 2006 for his dissertation entitled “New Aspects of the Quantum Geometric Phase”. For his PhD thesis he received the Victor-Hess-Award from the Austrian Physical Society.

He received his undergraduate degree (Dipl.-Ing.) in Technical Physics from the Technical University of Vienna, Austria in 2003 and a Master’s of Science degree in Physics from Uppsala University, Sweden, in 2002.
