Quantum Technologies and IP Services

Dr. Sebastian Schmidt

I'm a trained physicist and patent attorney with a special interest in emerging technologies such as quantum technologies, neuromorphic computing and artificial intelligence. I obtained my Ph.D. in Physics from Yale University, USA. After completion of my PhD I was a visiting postdoctorial fellow at the Princeton Center for Theoretical Science (PCTS) before becoming a group leader and senior lecturer at the Swiss Federal Institute of Technology in Zurich (ETH). My research experience ranges from condensed matter and many-body physics to quantum optics and superconducting electronics.
