Counting photons emitted by a single quantum defect in diamond

We analyze the full counting statistics of photons emitted by a Nitrogen Vacancy center (NV) under non-resonant laser excitation and resonant micro-wave (MW) control. This allows to build a phenomenological model which relates the relevant physical parameters with the detected fluorescence. Furthermore, we can investigate the time correlations of the emitted photons and elaborate detection and polarization protocols to optimize the energy and time resources while maximizing the system sensitivity.
