Zoltán Zimborás

Project leader
Wigner Research Centre for Physics

Zimborás Zoltán leads the Quantum Computing and Information Research Group at the Wigner Research Centre for Physics. He obtained his PhD at the Eötvös University in Budapest and worked later at UPV Bilbao, University College London, and Freie Universität Berlin before returning to Hungary. His fields of interests include the theoretical aspects of quantum computing (quantum advantage schemes, gate decompositions and computational universality, variational quantum algorithms) as well as the practical implementation of quantum algorithms on actual quantum devices. He is a member of the board of QWorld, a non-profit organization that aims to develop teaching material (including open-source software) for quantum programming at all levels. Together with his colleagues, he developed new Quantum Information Processing university courses that actively use the online available quantum computer prototypes.
