分别用量子约化熵和量子相对熵研究了双二能级原子与单模真空场相互作用的纠缠动力学。结果表明:通过选择合适的系统参数可以实现双原子纠缠的放大与保持,可以制备出纠缠度为1的双原子纠缠态。
In this paper, the entanglement dynamics of two two-level atoms interacting with a single mode vacuum field is investigated. The results show that amplification and preservation of the entanglement of two atoms can be realized by selecting appropriate system parameters.
