摘要
提出了一种基于V型三能级原子和腔量子电动力学系统的量子纠缠态制备方案。在不同耦合参量条件下,数值分析了任意两腔之间的纠缠演化规律。研究结果表明,当原子以恒定速度通过空腔时,通过改变耦合腔间的耦合参量,可实现对腔间纠缠的控制。利用此方案可同时实现多分量量子纠缠态的产生和控制。
Abstract
A scheme for the preparation of quantum entangled states is proposed based on a V-type three-level atom and cavity quantum electrodynamics system. The dynamics of cavity-cavity entanglement is numerically analyzed under different coupling parameters. The research results show that the cavity-cavity entanglement can be mediated by varying the coupling parameters between cavities when the atom successively passes through the empty cavities at a constant speed. Moreover, this scheme can be utilized for the simultaneous generation and control of multi-component quantum entanglement states.
