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.

Fingerprint Fingerprint is based on mining the text of the person's scientific documents to create an index of weighted terms, which defines the key subjects of each individual researcher.
