Long-distance coherent quantum communications in deployed telecom networks
Nature, Published online: 23 April 2025; doi:10.1038/s41586-025-08801-wA twin-field quantum key distribution protocol based on optical coherence is deployed over a 254-kilometre commercial telecom network, demonstrating that coherence-based quantum communication can be aligned with existing telecommunication infrastructure.
