Quantum communication across a 250-kilometre optical-fibre network
Nature, Published online: 23 April 2025; doi:10.1038/d41586-025-01173-1Quantum communication over long distances can be achieved by exploiting a property of light called coherence. The coherence-based exchange of a ‘quantum encryption key’ over an optical telecommunications network demonstrates the feasibility of implementing a large-scale quantum network in existing telecommunications infrastructure.
