Summary on Grant Application Form |

Quantum Computation and Information is a vigorously active cross-disciplinary field drawing upon quantum physics, theoretical computer science and communication science. Its scope ranges from deep fundamental issues in physics to prospective commercial exploitation by the computing and communications industries. Quantum mechanics gives rise to entirely new modes of information processing and communication. I have contributed several seminal results in recent years. Quantum computers have the ability to perform computational tasks exponentially faster than any classical device. This most fundamental result was first shown in 1992 by Deutsch and myself. I was a co-discoverer of the process of quantum teleportation which has led to the recognition of the central role of entanglement in quantum information theory. Subsequently I have contributed significantly to the large volume of recent work on entanglement in the context of mixed states. With Schumacher and others during 1994-1997 I developed the quantum source coding theorem, one of the cornerstones of the subject, and resolved a 25 year old conjecture characterising the classical capacity of a noiseless quantum channel. I was co-author of the earliest proposed quantum error correction scheme.The field is presently in a particularly buoyant and exciting state so that a Senior Research Fellowship at this time would be especially valuable. My proposed research topics target central seminal issues which would significantly influence the future course of the subject. I propose to develop new quantum algorithms investigating computational tasks which are believed intractable for classical computation. I will aim to characterise more clearly the origin of quantum computational speedup and its relation to classical complexity. I will continue to study entanglement for mixed states especially bi-partite and tri-partite systems. This is closely related to many open problems of the capacity of noisy quantum channels and tri-partite entanglement is beginning to emerge as a phenomenon of considerable novel applicability.
