| 摘 要： | 研究拉曼耦合玻色-爱因斯坦凝聚原子系统,在初始态具有量子相干性时纠缠相干态的生成,讨论了初始量子相干性对所生成的纠缠态的影响,指出初始量子相干性只影响所生成的纠缠相干态各组分之间的相位,不影响它们的振幅.

| Abstract: | Influence of initial quantum coherence on quantum entanglement in Raman coupling Bose-Einstein condensates (BECs) was investigated. Quantum dynamics for the situation of BECs being initially an entangled coherent state was studied. It was found that the initial quantum coherence of BECs only affects the relative phases between components not the amplitudes of the components. |
