Abstract: Indistinguishable single photons in the telecom-bandwidth of optical fibers are indispensable for long-distance quantum communication. Solid-state single photon emitters have achieved excellent performance in key benchmarks, however, the demonstration of indistinguishability at room-temperature remains a major challenge. Here, we report room-temperature photon indistinguishability at telecom wavelengths from individual nanotube defects in a fiber-based microcavity operated in the regime of incoherent good cavity-coupling. The efficiency of the coupled system outperforms spectral or temporal filtering, and the photon indistinguishability is increased by more than two orders of magnitude compared to the free-space limit. Our results highlight a promising strategy to attain optimized non-classical light sources.

Frequency conversion between microwave and optical photons is a key enabling technology to create links between superconducting quantum processors. We propose a microwave-optical platform based on long-coherence-time superconducting radio-frequency (SRF) cavities. We show that the fidelity of heralded entanglement generation between two remote quantum systems is enhanced by the low microwave losses.
