Quantum Information - Research Group Michael Walter

In our research group we explore the implications of quantum mechanics on the theory of computing. Quantum computers do not simply compute faster, but operate using completely different principles than ordinary “classical” computers - this requires completely new ideas. In addition, we investigate interdisciplinary applications of quantum information to problems in other areas of computer science, mathematics, and theoretical physics. We cordially invite you to get to know our international team and to learn more about our research.
