中文摘要
    :考虑一对纠缠的二能级原子之一与单模腔场发生双光子共振相互作用,经腔QED演化后,对腔场进行光子探测,通过操纵相互作用的时间和光场参数以及初态两纠缠原子的纠缠度,可远程调控腔外原子表现出更强的非经典效应,如原子的偶极压缩;同时使用相同的方法对远程控制的信道-原子间的纠缠演化也进行了控制,从而更有效地实现对原子量子特性的控制.并且发现原子的压缩和原子间的纠缠存在一定的对应关系.
英文摘要
    By considering the resonant interactions between one of two-level atoms in entangled state with a single mode and double-photon cavity field, and with the help of the evolution of cavity QED, the photon detection for cavity field is carried out. Through controlling the interaction time and the parameters of light fields as well as the entanglement degree of two entangled atoms in the initial state,the stronger non-classical effects of the atoms outside the cavity, such as atomic dipole squeezing phenomenon, are controlled. Simultaneously, using the same method, the entanglement evolution between two atoms as the channel of the long-distance controlling is also controlled. Thus, the control of quantum characteristics for two-atom system is achieved effectively. And the relation of entanglement and squeezing is found.
