Anton Frisk Kockum

Associate Professor at Applied Quantum Physics

Anton Frisk Kockum is a researcher working on various aspects of quantum optics and quantum information, including circuit quantum electrodynamics, ultrastrong light-matter coupling, quantum acoustics, and quantum machine learning. Anton received his Ph.D. degree in physics from Chalmers University of Technology in 2014. He then moved to Japan to be a postdoctoral researcher in the group of Franco Nori at RIKEN, where he was supported for two years through a Japan Society for the Promotion of Science (JSPS) Fellowship. In 2018, he moved back to Sweden, taking up a permanent position as a researcher at the Wallenberg Centre for Quantum Technology. Here, he mainly works on theoretical projects that contribute to the building of a quantum computer and to understanding what programs should be run on such a computer.
