Quantum Networking Breakthrough Points to Key Security Gains

Researchers from NYU, in collaboration with Qunnect and Cisco, demonstrated entanglement swapping across commercial fiber in New York City, proving quantum signals can be distributed over existing telecommunications infrastructure; the report highlights cybersecurity implications such as quantum key distribution, physical-layer security advantages over algorithmic encryption, and the need for software orchestration and hardware stabilization, but it does not report any cyber incident or active threat.
