“…However, the HBT test uses only single measurement layout among many where the nonclassicality of single photon states can manifest itself. Probably, many other linear optical (LO) schemes with single photon detectors can manifest single photon nonclassicality differently to that HBT test [17][18][19][20].…”

Single photon sources are necessary for optical quantum technology. The nonclassicality of emitted single photons manifests itself in diverse experiments and applications. The applications already require different nonclassical aspects of single photons, however, a suitable hierarchy of criteria is missing. We propose variable experimental tests, based on adjustable linear optical networks and single photon detectors, giving a hierarchy of such nonclassicality criteria. The hierarchy goes beyond Hanbury-Brown-Twiss test of photon antibunching and allows us to compare faithfully quality and performance of single photon sources via their nonclassical properties.

The efficient certification of nonclassical effects of light forms the basis for applications in optical quantum technologies. We derive general correlation conditions for the verification of nonclassical light based on multiplexed detection. The obtained nonclassicality criteria are valid for imperfectly balanced multiplexing scenarios with on-off detectors and do not require any knowledge about the detector system. In this sense, they are fully independent of the detector system. In our experiment, we study light emitted by clusters of single-photon emitters, whose photon number may exceed the number of detection channels. Even under such conditions, our criteria certify nonclassicality with high statistical significance.

“…In previous works, we have shown that the binomial form requires a reformulation of nonclassicality conditions [24,28]. Moments of the click counting statistics can be used to identify quantum correlations -even between multiple detector systems.…”

“…Based on the variance of these statistics, it is possible to identify in theory and experiment nonclassical, i.e. sub-binomial, light [24,25]. A source of correlated photon pairs together with the considered class of detectors can be used, for example, to identify spatial correlations [26][27][28] or to perform a detector calibration [29,30].…”

We derive an analytical description for quantum state preparation using systems of on-off detectors. Our method will apply the true click statistics of such detector systems. In particular, we consider heralded quantum state preparation using correlated light fields, photon addition, and photon subtraction processes. Using a post-selection procedure to a particular number of clicks of the detector system, the output states reveal a variety of quantum features. The rigorous description allows the identification and characterization of fundamentally unavoidable attenuations within given processes. We also generalize a known scenario of noiseless amplification with click detectors for the purpose of the preparation of various types of nonclassical states of light. Our exact results are useful for a choice of experimental parameters to realize a target state.
