Chair for Quantum Information - 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.

How To Get Started?


  • June 2023: Welcome Simon Schmidt, who just joined our group as a postdoctoral researcher!

  • April 2023: Welcome to three new group members! Amalia Böttger will be working on a Master’s project on quantum algorithms. Luca Witt will be working on a Bachelor’s project and join the QuBRA project. Vladimir Lysikov just joined as a postdoctoral researcher to work on our ERC project on “Symmetry and Optimization at the Frontiers of Computation”.

  • Feb 2023: Welcome to our team, Janine Hein!

  • Feb 2023: Welcome Tianwei Zhang, who just joined our group as a CASA PhD student to work on the CASA Fundamental Research Project “Cryptography in Light of Quantum Information”.

  • Jan 2023: Congratulations Freek Witteveen for being awarded the Stieltjesprijs for the best PhD thesis in Mathematics in the Netherlands. Freek obtained his PhD in our group with a thesis on “Quantum information theory and many-body physics”.

  • Jan 2023: Welcome Samuel Crew, who just joined our group as a postdoctoral researcher!

  • Aug 2022: Welcome Anurudh Peduri, who just joined our group as a PhD student as part of the QuBRA team!

  • Aug 2022: Together with Andris Ambainis and David Gross, we organized a Bad Honnef School on “Quantum Computing” (August 14-19, 2022) with a fantastic lineup of speakers. See here for more information and material.

  • June 2022: Together with Giulio Malavolta, we started organizing the Theory Colloquium. The talks in this series highlight exciting areas of current theoretical computer science research. All interested parties are cordially invited!

  • May 2022: Very pleased about the start of our ERC Starting Grant on “Symmetry and Optimization at the Frontiers of Computation”. We’re still hiring!

  • Jan 2022: Our BMBF project QuBRA is starting. We’re hiring!
