Paper Abstract

A realistic model for a photon source based on postselection from correlated photon pairs produced by parametric frequency down-conversion is suggested. Its efficiency in producing approximation of single photon states is examined. The application of such source in quantum key distribution schemes is discussed and comparison with currently used sources of photons is given. Future prospects of this type of photon source are outlined.
