Quantum Information is concerned both with the fundamental science of quantum systems and with how one can use quantum resources to perform computational and other information processing tasks. It is a new field and one of the most exciting and dynamics areas science and technology. A notable feature of this area is its interdisciplinarity and physicists, mathematicians, computer scientists and engineers have made major contributions. Deep links have been forged between the previously unrelated disciplines of quantum physics and computer science/information theory. On the one hand there have been insights into fundamental issues in physics. On the other, totally new methods of computation, communication and information processing have emerged.
In the Mathematics department we are interested in all theoretical aspects of quantum information science including foundations, non-locality, entanglement, information theory, cryptography and computation.
We are part of the interdisciplinary Bristol Quantum Computation and Information group which involves four departments: Computer Science, Electrical Engineering, Mathematics and Physics. We are also involved with the new initiative, the Bristol Centre for Complexity Sciences. In addition we collaborate with many groups world-wide including those in Amsterdam, Brussels, Cambridge, Geneva, Gdansk, IBM, MIT, Tokyo and Waterloo.
