Suitability of solid-state platforms as sources of $N$-photon bundles
Year: 2021
Type: preprint
Abstract: $N$-photon bundles constitute a class of highly nonclassical quantum states of light. They are a specific type of photon emission, where light quanta are released from a cavity only in groups of $N$ particles with a characteristic photon number statistics that may be taken as their fingerprint. We consider two solid-state cavity quantum electrodynamics (cQED) systems in terms of their suitability as emitters of $N$-photon bundles. As one example, we consider a semiconductor quantum-dot--microcavity system coupled to longitudinal acoustic phonons. There, we find the environmental influence to be detrimental to the emission of $N$-photon bundles. The other example is a superconducting qubit inside a microwave resonator. In these systems, pure dephasing is not important and an experimentally feasible parameter regime is found, where bundle emission can be observed.
