Single‑Photon Group

Group Leader:

Professor Gerald S. Buller

Depth Imaging

Measuring the distance to faraway objects, and building depth profiles of them, with low, eye‑safe levels of optical power.

Quantum Information

Securing private communications and verifying message authenticities with quantum mechanics.

Single‑Photon Detectors

Accurately and efficiently measuring the smallest possible unit of light. We develop novel detectors for use with telecommunications wavelengths.

About Us

What we do

Along with our research partners we investigate time‑correlated photon‑counting technology and applications. The group is actively pursuing research in photon‑counting detectors, especially at wavelengths > 1000 nm.

The photon‑counting applications studied include time‑resolved photoluminescence, time‑of‑flight imaging/ranging and quantum key distribution.

Where we're based

The Single‑Photon group is based in the Institute of Photonics and Quantum Sciences, part of the School of Engineering and Physical Sciences at Heriot–Watt University, Edinburgh, Scotland.

The Institute of Photonics and Quantum Sciences (IPaQS) carries out broad range of world‑leading research in photonic physics, engineering photonics and quantum sciences.
