双模SU(1,1)相干态与原子相互作用中的量子纠缠
ENTANGLEMENT IN THE INTERACTION BETWEEN TWO-MODE SU(1,1) COHERENCE STATES AND ATOM
【摘要】 考虑双模SU( 1,1)相干态与二能级原子相互作用 ,分别用量子约化熵和量子相对熵研究了该系统双模SU( 1,1)相干态与原子间的纠缠以及双模SU( 1,1)相干态的模间纠缠 ,分析了SU( 1,1)双模光子数差和光场失谐量对场—原子纠缠和模间纠缠的影响 .
【Abstract】 Considering the interaction between two-mode SU(1,1) coherence states and a two-level atom,we investigate the entanglement of field-atom and one of two modes of field using the quantum reduced entropy and quantum relative entropy,respectively.The influence of two-mode photon number difference and detuning on the evolution of the entanglement of field-atom and one of two modes of field has been discussed.
