摘要： The two-mode photon-added state defined by |ζ,q;m>=a+mb+m|ζ,q> up to a normalization constant is introduced, where |ζ,q> is a pair coherent state and m an integer. It is shown that the fields in such a state have remarkable quantum features such as sub-Poissonian statistics, violations of Cauch-Schwarz inequalities, correlations in the number fluctuations and squeezing. We examine the influence of photon-adding on the properties of pair coherent of cavity quantum electrodynamics.

Abstract: The two-mode photon-added state defined by |$\zeta$,q;m>=a+mb+m|$\zeta$,q> up to a normalization constant is introduced, where |$\zeta$,q> is a pair coherent state and m an integer. It is shown that the fields in such a state have remarkable quantum features such as sub-Poissonian statistics, violations of Cauch-Schwarz inequalities, correlations in the number fluctuations and squeezing. We examine the influence of photon-adding on the properties of pair coherent of cavity quantum electrodynamics.
