Single photons can be detected by monitoring the change in voltage along a nanowire.

A superconducting nanowire single-photon detector (SNSPD) that can detect single photons at the wavelengths used for telecommunications was built at Heriot-Watt University and installed at NPL. This will help to support emerging quantum optics technologies for the telecommunications industry that place tough demands on single photon sources and detectors.
