    "abstract": "A reliable single photon source is a prerequisite for linear optical quantum\ncomputation and for secure quantum key distribution. A criterion yielding a\nconclusive test of the single photon character of a given source, attainable\nwith realistic detectors, is therefore highly desirable. In the context of\nheralded single photon sources, such a criterion should be sensitive to the\neffects of higher photon number contributions, and to vacuum introduced through\noptical losses, which tend to degrade source performance. In this paper we\npresent, theoretically and experimentally, a criterion meeting the above\nrequirements.",
