【Abstract】 Based on our previous work, the phase state and phase operator introduced by Pegg and Barnett are generalized to two-mode q-deformed circumstances. With the aid of numerical method, the phase probability distributions of q-deformed pair coherent state are investigated. It is shown that these probability distributions of the state are regulated by the parameters of phase, the q-number and the magnitude of |ξ|. Therefore, the q-deformed pair coherent state exhibits different quantum interference properties.更多还原
