We identify the parameter values for which these states have a negative non-singular P-function, implying they are nonclassical. We show that the states of the ``heralded photons'' generated via spontaneous parametric down conversion belong to this family, with the three parameters corresponding to the nonlinear gain and the losses in the signal and the idler channels. The thermal-difference states yield new benchmark states for the analysis of nonclassicality and quantum macroscopicity criteria.Lire moins >
