Leon Koch is currently working as a PhD Student on multi-qubit superconducting qubit platforms. He started his PhD in July 2020. Before he worked in the group of Dieter Kölle and Reinhold Kleiner at the University of Tübingen. During his Master studies, he worked on the positioning of magnetic nanoparticles at superconducting quantum interference devices (SQUIDs).
