China Telecom Quantum Group has launched what it claims is the world's first commercial cryptography system that is 'impossible to hack,' even by quantum computers. The system features a three-layer architecture designed for enhanced information protection.
The system, developed by China Telecom Quantum Group, integrates Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) for comprehensive quantum security. This architecture supports real-time communications, data protection, and identity authentication. The company demonstrated the system by completing a cross-regional quantum-encrypted phone call over 1,000km between Beijing and Hefei.
With the rapid advancement of quantum computing, traditional encryption systems face vulnerabilities. China Telecom has also launched Quantum Secret, a quantum-secure instant messaging platform, and Quantum Cloud Seal, a platform for government approvals and enterprise workflow management. These platforms have already seen broad industry adoption. The company has built quantum metropolitan area networks in 16 key cities, forming a nationwide quantum-secure communication backbone.
