论文摘要
在这项工作中，研究了由外部经典场驱动的移动两颗粒系统的纠缠动力学，其中移动两颗粒系统与零温度共同环境耦合。当总兴奋数为一个时，可以使用穿着状态的基础来获得密度算子和纠缠的分析表达式。我们还详细讨论了不同参数对纠缠动态的影响。结果表明，经典驾驶不仅可以保护纠缠，还可以有效地消除量子速度的影响和对量子纠缠的失调的影响。
In this work, the entanglement dynamics of a moving-biparticle system driven by an external classical field are investigated, where the moving-biparticle system is coupled with a zero temperature common environment. The analytical expressions of the density operator and the entanglement can be obtained by using the dressed-state basis when the total excitation number is one. We also discuss in detail the effects of different parameters on the entanglement dynamics. The results show that the classical driving can not only protect the entanglement, but also effectively eliminate the influence of the qubit velocity and the detuning on the quantum entanglement.
