我们提出了一个纠缠纯化协议（EPP），用于纯化嵌入单面光腔中的分离原子。该协议工作在错误检测模式下，反射系数仅作为全局系数出现，成功或失败的情况由光子的检测来预示，这些优点使得协议具有更强的鲁棒性和实用性。我们讨论了协议的性能与当前的实验参数，结果表明，目前的EPP的成功概率是相对较高的。EPP可以为未来的量子中继器和量子网络提供有前途的构建块。
We propose an entanglement purification protocol (EPP) for purifying separate atoms embedded in single-sided optical cavities. The protocol works in an error-detected pattern, the reflection coefficients only appear as a global coefficient, the success or failure cases are heralded by the detection of photons, these merits make the protocol more robust and practical. We discuss the performance of the protocol with current experimental parameters, the results show the success probability of the present EPP is relatively high. The EPP could provide a promising building block for quantum repeaters and quantum networks in the future.
