摘要： A quantum communication system including an emitter and a receiver, the emitter including an encoder and at least one photon source and being configured to pass a signal pulse and a reference pulse, which are separated in time, through the encoder and output the signal pulse and the reference pulse. The reference pulse has a higher probability of containing more than one photon than the signal pulse. The receiver includes a decoder and at least one detector for measuring the signal pulse and the reference pulse.

摘要： An optical device which can operate as a single photon emitter 1, comprising a three dimensional optical cavity 7 which spatially confines a photon to the order of the photon wavelength in all three dimensions. The cavity 7 is configured to define preferred emission direction for photons entering the cavity. A photon can be supplied to the cavity using a quantum dot 5. Strong coupling can occur between the cavity 7 and the quantum dot 5 which causes the formation of two hybridised modes. Switching on an off the coupling by irradiating the device with radiation having an energy equal to that of one of the hybridised modes allows the device to act as an optical switch.
