Photon detection. Optical table containing lasers, beam delivery elements and optical fibres used to prepare and detect single photons. The detection of single photons has an application in quantum key distribution, which uses photons and the principle of entanglement to securely encrypt and transmit data. Photographed at the National Physical Laboratory in Teddington, UK.
