The CQIF research group's contributions to the theories of quantum computation and quantum cryptography include pioneering work on the relationship between physics and computation and the qualitative distinction between classical and quantum computing, the invention of relativistic quantum cryptography, the first secure bit commitment protocol, and the discovery of secure cryptography based on the no-signalling principle.

Our research interests also currently include foundational questions in quantum information theory, quantum theory, probability theory and quantum gravity, the theory of quantum channels, and novel cryptographic applications of quantum information.

More information can be gleaned from our most recent papers, and individual descriptions of research interests.
