City-Scale Quantum Encryption: Successful Demonstration of QKD over 50km

Securing the Metropolis

For the first time, quantum encryption has been successfully demonstrated over an entire city-sized distance (50km+) using standard fiber infrastructure...

Technical Achievements:

• Quantum Key Distribution (QKD): Real-time key exchange with zero intercept risk.
• Fiber Stability: New phase-correction algorithms to handle urban thermal noise.
• End-to-End Latency: Successfully integrated with existing 5G core networks.
