Entangled Quantum Emitters in the Presence of a Metallic Nanodisk

Abstract

Ultra-thin noble metal nanodisks facilitate high entanglement between distant quantum emitters (QEs). The ultra-thin noble metal nanodisk supports localized plasmon resonances; when these modes are excited high Purcell factors, of a single QE, and high coupling values, between a pair of QEs, are observed. We present that the entanglement time of the QEs surpasses the relaxation time of the individual QEs interacting with the metallic disk and reach the steady state faster than the case the QE are placed in free-space.
