| 摘 要： | 研究了一对纠缠的全同二能级原子在初始纠缠度不同时，与单模真空场相互作用的三体量子纠缠。结果表明：初始时刻两原子间纠缠度越大，体系的三体纠缠量震荡越激烈，达到最大纠缠量次数越多；并且随原子间耦合量大于原子与场的耦合量，三体纠缠量将会减小。

| Abstract: | The case that one of the two entangled identical two-level atoms interacts with a single-mode field among three-body entanglement was mainly considered. The results show that in initial the more the degree of entanglement of the two entangled atoms have, the more oscillation of the entanglement measure will have,and the more times of the maximally entanglement measure will obtain. Meanwhile, it was found that entanglement measure will be reduced when atomic coupling coefficient is larger than coupling coefficient between field and atom. |
