Roger Colbeck is Professor of Quantum Information Theory in the Department of Mathematics at King's College London.

He did his PhD in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, and held a Junior Research Fellowship at Homerton College, Cambridge, and post-doctoral positions at ETH Zurich in Switzerland and the Perimeter Institute for Theoretical Physics in Canada. Prior to joining King's he was a Professor of Mathematics at the University of York.

Research interests

Roger's main area of research is quantum information, which tackles the question of what makes quantum theory more powerful than classical theory for information processing, and how to exploit it. In particular, Roger works on device-independent quantum cryptography, which exploits entangled quantum particles to enable a new provably secure means of sending secret messages. He is also interested in the foundations of quantum mechanics, where his work connects to the question of what makes quantum theory special within a wider set of theories.
