基于腔QED技术的原子态纠缠纯化方案(英文)

Entanglement purification for atomic states via cavity QED

基于两能级原子与单模腔场之间的失谐相互作用,我们提出了一个有效的且能够纯化任意未知原子纠缠态的纠缠纯化方案。将量子逻辑门(Phys.Rev.Lett.74,4087(1995))和纠缠纯化(Phys.Rev.Lett.76,722(1996))的理论研究的最新进展相结合提出了一个在实验上可行的纠缠纯化物理方案。

In this paper, we propose a feasible entanglement purification scheme for an arbitrary unknown atomic entangled states, which is mainly based on the dispersive interaction between two-level atoms and cavity modes. This proposal is a combination of progresses on quantum logic gates （Phys. Rev. Lett. 74,4087（1995）） and the pure theoretical entanglement purification scheme（Phys. Rev. Lett. 76, 722（1996））.
