TH Colloquium - How to test quantum theory with thought experiments

ABSTRACT
Quantum theory is one of our most accurate theories ever when it comes to the description of small systems. It is therefore often assumed that the theory can equally well be applied to large objects, sometimes even astronomical ones like black holes. In my talk I will present a thought experiment that indicates that the range of validity of (current) quantum theory may be limited to small systems.
(The talk is based on work with Daniela Frauchiger and Nuriya Nurgalieva.)

BIO
Renato Renner graduated in theoretical physics and completed his PhD in the area of quantum cryptography in 2005. After spending two years in the UK, where he was a HP research fellow in the Department for Applied Mathematics and Theoretical Physics at the University of Cambridge, he joined the ETH Institute for Theoretical Physics as a professor, where he is heading the research group on Quantum Information Theory. His research interests are in the area of quantum information science, quantum thermodynamics, and the foundations of quantum physics.
