摘　　要：光纤耦合的腔量子电动力学系统是一个完美的理论模型,可以实现决定性的量子信息过程.该文综述了最近在光纤耦合的腔量子电动力学系统中实现分布式量子信息处理的工作.讨论了如何在该系统中实现量子态传输、纠缠分配和量子逻辑门,并概述了多种不同的方案,如共振耦合、绝热操控、虚激发过程.最后,讨论了这个方向上的实验进展.Fiber-coupled cavity QED system is a perfect theoretical model to study the deterministic distributing quantum information processes. Recent works on distributing quantum information processing in fiber- coupled cavity QED systems were reviewed in this paper. In this review, quantum state transfer, entanglement distribution, quantum logic gates and et al. in this system were discussed. The several types of the schemes, such as resonant interaction, adiabatic passage, and virtual-excitation processes were summarized. Finally, the experimental progresses in this direction were discussed.
