Abstract
The photon-number distribution of an output state from a single-photon source using gated spontaneous parametric downconversion is analyzed in detail. For an improved experimental result of , it is found that is restricted by the optical loss of the signal photon path (62%) and the cause of nonzero is the imperfection of the optical shutter for gating. A method by which to reconstruct the photon-number distribution via photon-counting measurement is also presented.
