This is a major research area in the
Centre
for Quantum Computer Technology.
I am interested in how super-selection rules (dynamical constraints)
impact upon quantum information processing. I am also interested in
entanglement issues, in particular how the Einstein-Podolsky-Rosen
paradox from 1935 can be formalized, and how it can be tested
experimentally in novel ways that may apply to more secure
communication in quantum cryptography.
