Quantum plasmonics is a rapidly growing field of research that involves the study of the
quantum properties of light and its interaction with matter at the nanoscale. Here, surface …

Nearly 30 years ago, two-photon interference was observed, marking the beginning of a
new quantum era. Indeed, two-photon interference has no classical analogue, giving it a …

A single photon can be coupled to collective charge oscillations at the interfaces between
metals and dielectrics forming a single surface plasmon. The electromagnetic near-fields …

Surface plasma waves on metals arise from the collective oscillation of many free electrons
in unison. These waves are usually quantized by direct analogy to electromagnetic fields in …

Surface plasmon polaritons (plasmons) are a combination of light and a collective oscillation
of the free electron plasma at metal/dielectric interfaces. This interaction allows …

Surface plasmon polaritons (SPPs) are electromagnetic excitations coupled to electron-
charge density waves at metal-dielectric interfaces. They have recently been found to …

We use frequency-entangled photons, generated via spontaneous parametric down
conversion, to measure the broadband spectral response of an array of gold nanoparticles …

Following the recent observation of localized phonon polaritons in user-defined silicon
carbide nanoresonators, here we demonstrate strong and coherent coupling between those …

In this work, the on-chip quantum interference of two single surface plasmons is achieved
using dielectric-loaded surface-plasmon-polariton waveguides. The high visibility (greater …

Quantum plasmonics is a field of research combining plasmonics with quantum optics and
investigates interactions between photons and metallic nanostructures. So far, it has been …
