基于腔结构的可控量子纠缠

Controllable Quantum Entanglement Based on Cavity Structure

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。

A scheme for the preparation of quantum entangled states is proposed based on a V-type three-level atomand cavity quantum electrodynamics system.The dynamics of cavity-cavity entanglement is numerically analyzedunder different coupling parameters.The research results show that the cavity-cavity entanglement can be mediatedby varying the coupling parameters between cavities when the atom successively passes through the empty cavities ata constant speed.Moreover,this scheme can be utilized for the simultaneous generation and control of multi-component quantum entanglement states.
