Abstract
The aim of this proposal is to develop new absolute standard radiation sources, which exploit the discrete and quantum nature of photons, and the necessary metrological infrastructure. These sources are based on single-photon emitters with calculable photon emission rate and high purity, i.e. very low multiple photon emission probability. Such sources hold promise as new quantum standards with large numbers of applications, e.g. calibration of single-photon detectors, realization of the SI base unit candela, quantum random-number generation, quantum key distribution, sub-shot noise metrology, quantum-enhanced metrology, and photon-based quantum computation.
