Identifying nonclassicality of multiphoton and multimode quantum states directly from experimental detector outcomes

We show experimentally how nonclassical statistics arise directly from the joint outcomes of multiplexed on-off detectors on two-mode, multiphoton optical states. This identifies a possible route to an entanglement witness using this scheme.
