摘要
用两个量子态的密度算符之间的距离并给合Von Neumann熵研究了在初始相干光场很强的条件下双光子Jaynes-Cummings模型(JCM)态的演化规律。
This article use the distamce between density operators and Von Neumann en-tropoy to Study the state evolution in the two-photon Jaynes-Cummings model with the cavity field initially in a coherent state with a large average photon number
