| 摘 要： | 运用全量子理论,研究双模压缩真空态与运动原子相互作用过程中,双模光场的模间纠缠性质,讨论了原子初态处于激发态时,原子运动和场模结构对模间纠缠性质的影响.结果表明,原子的运动速度和场模结构影响模间纠缠度,但不破坏模间纠缠演化的周期性.

| Abstract: | The quantum entanglement properties of the two-mode squeezing vacuum field interacting with the atomic motion via two-photon transition were studied based on quantum theory.The influences of atomic motion and the field structure on the quantum entanglement were investigated as the initial state of atom is in the excited state.The results showed that the degree of entanglement between two mode vacuum fields is influenced by the values of velocity of the atomic motion and the structure of the field-mode,but the periodic evolution of the entanglement properties cannot be destroyed. |

| Keywords: | quantum entanglement two mode vacuum field atomic motion field-mode structure (relative) entropy |
