The construction of a single-photon source by use of gated parametric fluorescence is reported with the measurement results of the photon number distribution. A beamlike twin-photon method is used in order to achieve high-collection efficiency. The estimated probability P(1) to find a single photon in a collimated output pulse is 26.5% at a repetition rate of 10 kHz when the effective quantum efficiency of 27.4% in the detection setup is compensated.

  15. For example, a single-photon source with the photon number distribution {P(0), P(1), P(2)} = {0.7, 0.3, 0} is much more useful for quantum cryptography than that with {0.5, 0.4, 0.05}, where P(n) is the probability to find n photons in a pulse. Those photon number distributions, however, yield the same Fano factor F = 0.7.
