Title: Next-generation single photon sources for satellite-based quantum communication

Abstract: We present a room temperature single photon source based on a color center in hexagonal boron nitride for satellite-based quantum networks. The resonator-coupled emitter is characterized by a narrowband tuneable spectrum, high photon purity, and high quantum efficiency. The photon source is currently integrated on a 3U CubeSat to qualify it for use in a future satellite-based global quantum-encrypted network. The satellite also performs a fundamental test of quantum gravity.
