中文摘要：

提出借助单原子囚禁的开放腔QED系统实现光子间的可控相位门的方案.该方案的优点是采用探测光与控制光处于不同的空间模式,避免了在实验上为了同时处理两光场而使用光分束器所导致的光子损失,这有利于实现可扩展的光量子网络.

英文摘要：

A scheme for the realization of the controlled phase-flip gate is proposed, which is via opened cavity QED system with trapped single atom. The advantage of the proposal is to avoid lossing photon due to the use of beam splitter which is to deal with the two light field at the same time in experiment. So it is beneficial to implement scalable quantum networks with photonic qubits.
