Nonclassicality Phase-Space Functions: More Insight with Fewer Detectors
Nonclassicality Phase-Space Functions: More Insight with Fewer Detectors
Systems of on-off detectors are well established for measuring radiation fields in the regime of small photon numbers. We propose to combine these detector systems with unbalanced homodyning with a weak local oscillator. This approach yields phase-space functions, which represent the click counterpart of the $s$ parametrized quasiprobabilities of standard …
