Personal profile

Research interests

My research is focussed on coherent light-matter interactions for quantum information processing and photonic networking.

In particular, I am developing quantum memories to enable temporal multiplexing of non-deterministic optical quantum gates.

Other research interests include photodetection, giant optical non-linearities, wavelength conversion, quantum communications, random number generation, and coherent transport.
