Abstract :
In this paper, we use the Wigner function in order to determine the photon number statistics of a heralded single-photon source constructed from a photon-pair source using four-wave mixing in optical fibers. Having this result, we discuss the performance of a quantum key distribution system when this kind of single-photon source is employed.
