| 摘 要： | 运用量子信息熵理论研究了K err介质中双光子J-C模型中场熵压缩性质,讨论了K err介质与原子初态对场熵压缩特性的影响.结果表明强K err介质相互作用减小了场熵的压缩深度,原子相干性也影响场熵压缩效应的存在和压缩深度.

| Abstract: | The entropy squeezing properties in the two photon Jaynes-Cummings model in a Kerr medium are studied by means of quantum information entropy,and the nonlinear interaction of the Kerr medium with the model field and the initial state of atoms on the field entropy squeezing are discussed.It shows that the nonlinear interaction of the Kerr medium can lead to a decrease in the squeezing depth.On the other hand,the squeezing time and the squeezing depth are influenced by the atomic distribution angle. |
