Abstract

Recently, macroscopic violation of classical Cauchy-Schwarz (CS) inequalities has been demonstrted experimentally [1], A new classification of macroscopic nonclassical light, “anti-Schwarz” light was proposed, in which one of the CS inequalities is violated [2], We predicted that the CS inequalities may be violated by “antiSchwarz” twin beams in the absence of a sub-shot noise intensity difference. This indicates that “anti-Schwarz” beams are different from conventional “quantum-correlated” twin beams generated from optical parameter down-conversion [3], The CS inequality (|g12(2)(τ)|2g11(2)(0)g22(2)(0)) can be expressed in terms of photon noise spectral densities as [2]
