Abstract

In this paper we study the effect of decoherence on the photon-added even/odd coherent states. For this purpose, the time-dependent Wigner function of the considered states during their interaction with the environment in zero temperature (that is called photon-loss channel) is obtained in the framework of standard master equation. Then, by analyzing the evolution of Wigner distribution of the mentioned states, the loss of nonclassicality behavior as a result of decoherence is clearly shown.
