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 { P ( 0 ) , P ( 1 ) , P ( 2 ) } = { 0.59 , 0.40 , 0.009 } , it is found that P ( 1 ) is restricted by the optical loss of the signal photon path (62%) and the cause of nonzero P ( 2 ) 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.
