Sub-Poisson-binomial light
Sub-Poisson-binomial light
We introduce a general parameter ${Q}_{\mathrm{PB}}$ that provides an experimentally accessible nonclassicality measure for light. The parameter is quantified by the click statistics obtained from on-off detectors in a general multiplexing detection setup. Sub-Poisson-binomial statistics, observed by ${Q}_{\mathrm{PB}}<0$, indicates that a given state of light is nonclassical. Our parameter replaces …
