Dominik Hangleiter | QuICS

Hartree Postdoctoral Fellow

3253 Atlantic Building

Dominik is a quantum scientist working at the interface between computer science, mathematics and physics, as well as the philosophy of quantum science. In his research, he explores the potential of analog and digital quantum computing devices from the theoretical perspective of computational complexity and classical simulation algorithms, and tries to understand the physical mechanisms underlying their speedups. In collaboration with experimental groups, he develops and applies resource-efficient characterization tools to help improve those devices. He also enjoys thinking about methodological aspects of science in general, and quantum science in particular from a philosophy of science point of view. Dominik studied physics, philosophy, and mathematics in Konstanz, Oxford and Munich, and received his Ph.D. from Freie Universität Berlin.
