    金属纳米结构表面等离激元与原子、分子和量子点等量子发射体的相互作用是近些年来量子光学研究的热点。金属纳米颗粒具有许多独特的性质，比如: 在其表面能激发表面等离激元, 可以将电磁场局域在其附近。量子发射体与金属纳米颗粒不同电磁激发模式的相互作用会引起新奇的物理现象。更有趣的是，在多个相互靠近的金属纳米颗粒系统中，能激发出耦合共振模式。这些耦合共振模式能引起量子发射体之间丰富的关联效应。本报告将从金属纳米结构表面等离激元构造的多比特量子逻辑门、量子纠缠、能量转移等角度对这些现象做相关介绍。

    In recent years, the interactions between surface plasmons of metallic nanostructures and quantum emitters like atoms, molecules and quantum dots have been the research hotspots of quantum optics. Metallic nanoparticle possesses many unique properties; for instance, the electromagnetic fields can be confined in the surface of the nanoparticle due to the excitation of plasmons. The interactions between quantum emitters and different electromagnetic excitation modes of nanoparticle can arise novel phenomena. More interestingly, in the closely spaced metal nanoparticle systems, coupling resonance modes could be excited. These coupling resonance modes can cause rich correlation effects between quantum emitters. This report is focused on the quantum correlation and energy transfer induced by interactions between multiple quantum emitters and nanoparticle cluster.
