Over the past ten years an increasing interest for improved single photon technology has been come up in research fields as diverse as optical quantum information technology, laser ranging, remote sensing, astronomy or biomedical imaging. In this context metrological validation of single photon sources and detectors are expected to have an immediate impact on further industrial needs of prospective...
One key element in further development of quantum information processing systems is the ability to prepare single photon states, which in practice is still difficult. While attenuated lasers obey Poissonian statistics, current single photon sources are imperfect, because their second order correlation function g(2)(t = 0) is non-zero, implying residual multiphoton emission [1]. Various experimental...
This work demonstrates the validation of a measurement equipment, such as a photodetector, by utilizing a single photon source that is based on laser fluorescence of nitrogen vacancies (NV-centers) in diamond. This validation method is done to further metrological characterisation and development of quantum technology. Measurement results and uncertainty analysis of the standard detector and photon...
