Roger Colbeck



Following research positions at Homerton College in Cambridge, ETH Zurich (Switzerland) and the Perimeter Institute for Theoretical Physics (Canada), I am now a lecturer in mathematics at the University of York.



My research spans many aspects of quantum information theory, as well as the foundations of quantum mechanics.  Much of my work connects the two. I find quantum information is a particularly interesting field because it brings together three major disciplines: mathematics, physics and computer science with the broad goal of understanding what power the laws of physics give us for processing information.

Within quantum information theory, I have worked on device-independent quantum cryptography and quantum random number generation, the use of quantum and relativistic protocols for secure computations, new uncertainty relations and constructing circuits for quantum computation.  In foundations, I have done work on the question of whether the world is random and whether there could be theories that improve on the predictions of quantum mechanics.

Many of these areas are suitable for PhD projects -- please get in touch if you are interested.

Available PhD research projects

I am principally offering projects in quantum cryptography (in particular device-independent protocols) or quantum foundations (understanding cause in quantum theory). However, I may be willing to take students who wish to look at other aspects of quantum information theory.
