增、减光子奇偶相干态的Wigner函数

Wigner functions for the photon-added and photon-depleted even and odd coherent states

利用Fock态表象下的Wigner函数定义,重构了增、减光子奇偶相干态的Wigner函数,并据此讨论了它们的非经典性质.结果表明增光子奇偶相干态总呈现出非经典特征,而减光子奇偶相干态分别仅在k为偶数和奇数时呈现出非经典特征.

By using the definition of Wigner function in Fock states representation, Wigner functions for the photon-added and photon-depleted even and odd coherent states is reconstvucted. The results show that photon-added even and odd coherent states always demonstrate non-classical characteristics but photon-depleted even and odd coherent states demonstrate non-classical characteristics only when k take odd and even number respectively.
