A consortium of research institutions has demonstrated continuous, unhackable data transmission across an intercity fiber network using Quantum Key Distribution (QKD). The system maintained stable key generation rates over a 30-day continuous testing phase.
Signal Noise Mitigation
Advanced single-photon detectors and active phase-compensation algorithms enabled signal transmission over existing commercial telecommunication fiber without requiring cryogenic cooling intermediate nodes.
Commercial Readiness
Financial institutions and defense contractors are monitoring the deployment as a defense mechanism against future post-quantum cryptographic threats.
