We continue to feature some of our experimental physicists. In this episode, we talk to Jan Klos, PhD student and associated member of ML4Q. Jan - who is almost done with his PhD thesis - performed his project in the group of Hendrik Bluhm and Lars Schreiber at the JARA Institute for Quantum Information. In the episode, Chris talks with Jan about going from a Master project in simulating quantum dot spin qubits to a PhD project fabricating them. They also discuss outreach, student supervision, thesis writing and working with engineers.
