量子等离子体激元学（Quantum plasmonics）是近年来在量子光学和等离子体激元学（Plasmonics）（后者也可以被看作是金属结构的纳米光子学）两个领域的边界上出现的一个发展非常迅速的领域。纳米光子学关注纳米结构与光的相互作用，从而旨在提供更小长度尺度和更低能量要求的光子能力。但更重要的是，纳米光子学还旨在以前所未有的高强度和/或亚波长空间分辨率设计光-物质相互作用。后者通常涉及使用金属作为这些支持表面电磁模式（称为表面等离子体），其被限制在亚波长距离内的金属表面。在过去的十五年里，对所谓的“等离子体激元”的研究集中在等离子体激元电路上（由亚波长尺寸的波导和波导组件组成）、光学天线（作为远场和近场波分量之间的有效换能器，在体积上压缩并在强度上增强局部场），和表面增强光谱技术（如“表面等离子体共振感测”和“表面增强拉曼光谱”），涉及包括光子学、光电子学、材料科学、生物成像、医药和能源。
Quantum plasmonics is a very rapidly developing field that emerged recently at the border of two fields, both rich in fundamental physics and highly innovative in technology: quantum optics and plasmonics (the latter can also be viewed as nanophotonics of metal structures).Nanophotonics concerns with the interaction of nanostructures with light, thereby aiming at providing photonic capabilities at smaller length scales and lower energy requirements. But even more importantly, nanophotonics also aims at engineering the light–matter interaction at unprecedented high strengths and/or subwavelength spatial resolutions. The latter usually involves the use of metals as these support surface electromagnetic modes (known as surface plasmons), which are confined to metal surfaces within subwavelength distances. In the last fifteen years, studies in what became known as “plasmonics” have been concentrated on plasmonic circuits (composed of subwavelength-sized waveguides and waveguide components), optical antennas (as efficient transducers between the far-and nearfield wave components, squeezing in volume and boosting up in strength local fields), and surface-enhanced spectroscopic techniques (as “surface plasmon resonance sensing” and “surface-enhanced Raman spectroscopy”), with implications to diverse fields including photonics, optoelectronics, material science, bio-imaging, medicine, and energy.
