Query: Plasmon-enhanced generation of non-classical light   Strong light-matter interactions enabled by surface plasmons have given rise
to a wide range of photonic, optoelectronic and chemical functionalities. In
recent years, the interest in this research area has focused on the quantum
regime, aiming to developing ultra-compact nanoscale instruments operating at
the single (few) photon(s) level. In this perspective, we provide a general
overview of recent experimental and theoretical advances as well as near-future
challenges towards the design and implementation of plasmon-empowered quantum
optical and photo-emitting devices based on the building blocks of
nanophotonics technology: metallo-dielectric nanostructures and microscopic
light sources.
