Quantum information and computation, non-equilibrium statistical mechanics, generalised probabilistic theories, foundations of quantum theory
Dahlsten is also at the Clarendon Laboratory in Oxford. Previously he worked at the Institute for Theoretical Physics at ETH Zurich. He was trained at Imperial College. He is a Research Fellow of Wolfson College and a Lecturer of St Catherine’s College, both of Oxford University. He is one of the founders of a new approach to non-equilibrium statistical mechanics which is inspired by single shot information theory. He has also contributed several results on the foundations of quantum theory.
