Areas of expertise I am a quantum optician. I develop technologies for single photon optics, sources and detectors.

My colleagues and I have recently demonstrated quantum secure key exchange (quantum cryptography) over 23 km free space range.

I continue developing various single photon technologies including detectors, sources, conditional linear logic gates and long range quantum cryptography (maybe to satellites). Have also performed various pair photon interference experiments confirming the non-locality of quantum entanglement.
