Generation of NPT Entanglement from Nonclassical Photon Statistics
Abstract
With a product state of the form in = a|0>bb< 0| as input, the output two-mode state out, of the beam splitter is shown to be NPT whenever the photon number distribution (PND) statistics \p(na) \ associated with the possibly mixed state a of the amode is antibunched or otherwise nonclassical, i.e., if \p(na)\ fails to respect any one of an infinite of classicality conditions.
