摘　　要：腔量子电动力学是在单量子层次上研究光和物质相互作用,在光和原子的强弱耦合、量子相干以及量子信息等方面取得了巨大的成功。通过局域场增强效应,微纳光子结构可以极大地提高光和量子体系的耦合强度,给传统腔量子电动力学带来了新的研究机遇。文章综述了微纳尺度腔量子电动力学的基本原理、重要进展以及可能的应用,特别是在基于金属微纳结构的复合体系中的量子光学效应。这些研究工作不但丰富了光和物质相互作用的内容,还将为芯片上量子信息过程及其可扩展量子网络提供一定的基础。Cavity quantum electrodynamics(CQED) is the study of the interaction between light and matter at the single quantum level. It has achieved great success in explaining the strong or weak coupling between light and atoms, quantum coherence, quantum information, and so on. With the local field enhancement effect, micro-and nano-photonic structures can greatly enhance the interaction between light and quantum systems, which brings new opportunities for the study of traditional CQED. Here we review the basic principles, important progress, and possible applications of CQED at the micro/nanoscale, especially the quantum optical effects in metal-based nanophotonic structures. These studies not only enrich our understanding of the interaction between light and matter, but also provide a basis for on-chip quantum information processing and scalable quantum networks.
