Academic background
Robert de Keijzer completed his Bachelor and Master in Applied Physics and Applied Mathematics at Eindhoven University of Technology. In his master thesis, he explored and designed quantum algorithms for quantum chemistry applications, specifically focussing on pulse-based algorithms.
Research profile
As a PhD student at Eindhoven University of Technology, Robert de Keijzer works on designing quantum algorithms for the KAT-1 quantum computer, to be built in Eindhoven. Specifically, focussing on pulse based algorithms working efficiently in the NISQ-era. These algorithms are necessary as a stepping stone towarads universal quantum computing.
