摘　　要：采用数值计算法研究了纠缠双原子和相干光场相互作用中辐射光场光子数分布的演化特性。结果表明,通过和纠缠双原子的相互作用,使得不具有反聚束效应和光子亚泊松分布的相干光场获得了非经典特性。并且初始双原子间的纠缠强度越大,辐射光场的非经典性质越强,说明可以通过选择初始原子状态制备非经典辐射光场。The time evolution properties of photon distribution in the interaction of entangled double atoms and coherent field are studied by means of numerical calculation. The results show that the coherent field which has not photon anti-bunching and photon sub-Poisson distribution can gain these non-classical properties through the interaction with the entangled double atoms..And it is found that with the intensifying of entangle between initial state non-classical properties of photon distribution will increase corresponding,which indicates that non-classical light emission can be generated from the interaction of given entangled double atoms.
