We study fundamental aspects of quantum theory through the analysis of relevant information processing tasks and algorithms. We are interested in the formulation of physical principles in terms of information processing possibilities.
When the particles that make up a material are strongly-correlated, we theorists get a run for our money: qualitatively new behaviour emerges and the whole is a lot more than the sum of its parts. The theoretical description of matter in such challenging circumstances benefits from very close interaction with experimentalists. For this reason the University of Kent has set up, as part of the SEPnet collaboration, a small outpost of theorists at the ISIS Facility in the Rutherford Appleton Laboratory.
The group is involved in research on a wide spectrum of topics in quantum information science, including quantum communication, quantum cryptography, and theory of entanglement. The QIC group also actively works in the recently developing field at the interface of quantum many-body physics and quantum information. Other interests include realizable quantum computers in ultra-cold gases, and in quantum optical systems, and foundations of quantum mechanics.
