Welcome to The Photon Counting Group

The Photon Counting group is based in the School of Engineering and Pysical Sciences at Heriot–Watt University, Edinburgh, Scotland. We researche time–correlated photon–counting technology and applications. The group is actively pursuing research in photon–counting detectors, especially at wavelengths > 1000nm. The photon–counting applications studied include time–resolved photoluminescence, time–of–flight imaging/ranging and quantum key distribution.
