中文摘要：

运用全量子理论并结合数值计算方法，研究了三个二能级原子系统的量子特性．初始三原子处于W纠缠态，让其中的两原子A、B与相干态光腔场发生共振作用，经腔OED演化以后，对原子进行Bell基测量，通过调节相干态光场的强度和原子间的偶极相互作用，来控制腔外原子C的布居差演化；对相干态光场进行光子探测，通过改变探测到的光子数、相干光场参量和原子间偶极相互作用，来控制腔外原子C的偶极压缩，最终实现了远程操纵腔外原子非经典特性的目的．

英文摘要：

We use quantum theory and numerical method to study the non-local three-atom system quantum characteristic. The initial state of the three-atom system is on the three-body entangled W state,and the two atoms A, B can interact resonantly with a single-mode field in the coherent state. During the course of Cavity-QED evolution of the total system,we make Bell measurements to the atoms A and B. Through operating the intensity of the coherent field and the dipole-dipole coupling interaction between atoms A and B,we can control the atomic occupancy of atom C outside of the cavity. After taking photon detection to the coherent field,we can control C atomic dipole squeezing through manipulating the evolution time, the number of the detected photons, the parameter of coherent field and the dipole-dipole coupling interaction between atoms A and B. So we are easy to remotely control the quantum character of the atom outside of the coherent cavity.
