- Abstract: The extraordinary sensitivity of plasmonic sensors is well known in the
optics and photonics community. These sensors exploit simultaneously the
enhancement and the localization of electromagnetic fields close to the
interface between a metal and a dielectric. This enables, for example, the
design of integrated biochemical sensors at scales far below the diffraction
limit. Despite their practical realization and successful commercialization,
the sensitivity and associated precision of plasmonic sensors are starting to
reach their fundamental classical limit given by quantum fluctuations of light
-- known as the shot-noise limit. To improve the sensing performance of these
sensors beyond the classical limit, quantum resources are increasingly being
employed. This area of research has become known as `quantum plasmonic sensing'
and it has experienced substantial activity in recent years for applications in
chemical and biological sensing. This review aims to cover both plasmonic and
quantum techniques for sensing, and shows how they have been merged to enhance
the performance of plasmonic sensors beyond traditional methods. We discuss the
general framework developed for quantum plasmonic sensing in recent years,
covering the basic theory behind the advancements made, and describe the
important works that made these advancements. We also describe several key
works in detail, highlighting their motivation, the working principles behind
them, and their future impact. The intention of the review is to set a
foundation for a burgeoning field of research that is currently being explored
out of intellectual curiosity and for a wide range of practical applications in
biochemistry, medicine, and pharmaceutical research.
