UK Demonstrates First Long-Distance Quantum Network Integrating Entanglement and QKD Over 410 km Fibre

Researchers from the Universities of Bristol and Cambridge have successfully demonstrated the UK’s first long-distance quantum-secured data transmission, including a live quantum-encrypted video call, over a 410-kilometre fibre optic link. The achievement represents a major milestone in the development of a future quantum internet, integrating multiple quantum key distribution (QKD) technologies with existing classical communication […]
