摘　　要：将三个原子分别囚禁于用光纤连接的三个光腔中,通过光学开关控制腔场间的相互作用,并利用绝热技术制备了三粒子三维纠缠态。在整个制备过程中,原子-光腔-光纤系统仅在暗态空间中演化,从而有效地抑制了原子的自发辐射、腔场的泄漏以及光纤损耗等消相干因素的影响。The three-particle three-dimensional entangled evolutions,where three atoms are respectively trapped in state is generated by appropriately adiabatic three separated cavities with the optical fiber connection, the interaction between two cavities can be exactly controlled by the optical device. During the whole preparation process, the decoherence factors such as the atomic spontaneous emission radiation, cavity field leakage,and the fiber loss are efficiently suppressed since the atom-optical cavity-fiber system only evolves in the dark state space.
