经典场驱动下开放运动双粒子系统的纠缠动力学

Entanglement dynamics of an open moving-biparticle system driven by classical-field

Qilin Wang, Rongfang Liu, Hong-Mei Zou, Dan Long, Jia Wang

摘要:

研究了在经典外场作用下运动双粒子系统与零温公共环境耦合时的纠缠动力学.当总激发数为1时,利用缀饰态基可以得到密度算符和纠缠度的解析表达式。我们还详细讨论了不同参数对纠缠动力学的影响。结果表明,经典驱动不仅可以保护纠缠,而且可以有效地消除量子比特速度和失谐量对量子纠缠的影响。

英文摘要:

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.
