含有三参数的广义压缩态及其特性OACHSSCD

As an extension of ordinary squeezed states,a class of generalized squeezed states with three parameters is theoretically proposed by acting a complex evolution operator on vacuum,and their nonclas-sical properties are explored based on the sub-Poisson distribution,photon number distribution,entangle-ment entropy,and Wigner distribution function.The results show that,compared to ordinary squeezed states,the new generalized squeezed states exhibit more significant sub-Poisson distribution,entangle-ment,and squeezing characteristics when the three parameters take certain specific values.
