Tailoring the performance of WSe₂ quantum emitters via cavity quantum electrodynamics and coherent driving — •Ivan Solovev — Institute of Physics, Carl von Ossietzky University of Oldenburg, Oldenburg, Germany

The ability to create scalable arrays of bright and easily-fabricated single photon sources has sparked keen interest in Van der Waals materials, rendering them a promising platform for emerging quantum technologies. Here I will provide an overview how their performance can be substantially improved via integration into a tunable microcavity as well as exploiting resonant excitation schemes. The implementation of the monolithic Fabry-Pérot open cavity, operating in a weak coupling regime, enables the observation of phenomena such as Purcell enhancement of radiative decay, strain-induced tuning of the emitter energy and two-photon interference. An impact of phonons on dephasing and resulting indistinguishability will be discussed. Furthermore, the selective excitation in a coherent manner is achieved via resonant driving, leading to the observation of Rabi oscillations.
