Short CV

Following his studies in physics at ETH Zurich, Robert König received his PhD from the Department of Applied Mathematics and Theoretical Physics of the University of Cambridge, UK, in 2007. He subsequently worked as a postdoctoral scholar at the Institute for Quantum Information, Caltech, as well as the IBM TJ Watson Research Center. Prior to joining TUM as a Rudolf Mößbauer Tenure Track Professor, he was an assistant professor at the Institute for Quantum Computing of the University of Waterloo. Since 2015, he has been assistant professor at TUM.
