Abstract

We present a compact room temperature single photon source based on a color center in hexagonal boron nitride for future long-distance satellite-based quantum networks. The performance of this quantum light source is sufficient to outperform state-of-the-art laser-based decoy quantum key distribution protocols. The emitter is directly coupled to a photonic integrated circuit that routes the single photons to different experiments. This includes both a verification of the single photon source via measuring the photon statistics, as well as a fundamental test extended quantum theory in microgravity. The payload is currently being integrated on a 3U CubeSat and will be launched in 2024 as part of the QUICK³ mission.
