Welcome!

The Leeds Quantum Information Group (School of Physics and Astronomy, University of Leeds) conducts theoretical and experimental research into various aspects of quantum information processing, and into the implications of the quantum theory of computation for physics itself. The discovery that quantum physics allows fundamentally new modes of information processing has required the existing theories of computation, information and cryptography to be superseded by their quantum generalisations.

Our group currently consists of a Royal Society URF, three readers, a professor in theoretical and a professor in experimental Quantum Information. The topics covered by the group include physical realizations of quantum computation, communication and cryptography, entanglement and computational complexity, BECs and optical lattices, quantum optics, topological quantum computation, and foundations and applications of quantum information.

Nonlocality of a single particle Read an article by the group that is reported in Physics Web demonstrating the nonlocality of a single massive particle without experimental objections.
	A better than perfect match Read an article that appeared in Nature written by the group on entanglement, the feature Schrodinger called "the characteristic trait of quantum mechanics".
Entanglement heats up Read an article on research done by the group that appeared on Physics Web about the possibility of entanglement between photons and "large" objects at non zero temperatures. In this case the "large" object was a mirror.
	Cluster state quantum computer Read a paper proposing a cluster state quantum computer based on a cavity quantum electrodynamics implementation that appeared in New Journal of Physics.
