Abstract

Plasmonic nanostructures can enhance spontaneous emission rates by orders of magnitude, making solid-state single-photon emitters practical for quantum technologies. Strong confinement of the electric field allows plasmonics to achieve greater enhancement than dielectric cavities. Using nanopatch antenna structures and ultra-low loss epitaxial silver films, we demonstrated record brightness of single nitrogen vacancy centers. These results were extended to show that plasmonic enhancement could theoretically produce single photons at THz rates from a quantum emitter. By enhancing the emission rate to a sufficient degree, plasmonics will produce photons faster than the dephasing rate, thereby generating indistinguishable photons at elevated temperatures.
