Research

After several years of research on the foundations of quantum theory and quantum information, the scientific focus of our group shifted toward the interplay between quantum theory and space-time physics. In approaching these questions from new and still largely unexplored directions, we have been guided by the conviction that physical phenomena should be described in terms of operationally well-defined notions. This has led us to employ tools from quantum foundations and quantum information theory throughout our research.

Current reserach areas are:
Quantum reference frames
Indefinite causal structures
Wigner's friend thought experiment
Quantum theory and gravity
Reconstruction of quantum theory
Quantum to classical transition

Past research ares:
Quantum communication complexity
Bell's inequilities
Macroscopic entanglement witnesses
Information-theoretic foundations of quantum theory
