在两个分离NV色心之间实现纠缠和量子态传递的有效方案
首发时间:2014-01-08
摘要:提出了实现两个分离NV center之间纠缠态以及量子态传递的有效方案。这个方案利用两个回音壁模式的球型介质微腔作为中介,而这两个球型介质微腔可以通过倏逝场或者光纤锥波导耦合。我们从理论上推到出了制约此体系演化的有效哈密顿量,并证明了在一定条件下基于此耦合体系可以实现两个NV center之间的纠缠态以及量子信息的传递。

Efficient scheme for entangled state and quantum information transfer between two spatially separated nitrogen-vacancy centers
Abstract:An efficient scheme is proposed to achieve entanglement and quantum information transfer between two separated nitrogen vacancy (NV) centers with two whispering-gallery-mode (WGM) microresonators, which are coupled either by the evanescent fields of the WGM or by an opticalfiber-taper waveguide. Owing to the excellent characteristics of the coupled system, an effective Hamiltonian is derived theoretically, with which the preparation of entangled state and exchange of information between the NV centers can be achieved under appropriate conditions.
Keywords: quantum optics Entangled states quantum information transfer NV centers
