摘要
利用量子信息熵理论研究耦合双模 ＳＵ（１，１）相干态Ｊ－Ｃ模型的动力学特性．给出表示原子态变化的量子力学通道及表征量子通道传输原子初始信息能力的量子互熵．具体讨论了初始场的位相相干性和双模相干态参量对量子力学通道及量子互熵的影响．
We use the information entropy theory to study the dynamical properties for correlated two mode SU(l,1) coherent states in J-C model. We concretely give the quantum mechanical channel representing the state change of atom in the model, derive a general expression of the quantum entropy representing the capability of the channel transmitting atomic initial information, and examine the effects of the phase coherence and the state parameters of initial cavity field on the quantum channel and mutual entropy.
