Chinese firm launches ‘unhackable’ quantum cryptography system

China Telecom says its network has proved its worth with a 1,000km quantum-encrypted phone call.

China Telecom Deploys Hybrid Quantum-Safe Encryption System Across 16 Cities - Quantum Computing Report

China Telecom Quantum Group has launched a commercial-grade distributed cryptography system integrating quantum key distribution (QKD) with post-quantum cryptography (PQC). Designed to provide resilience against both current and future threats posed by quantum computing, the hybrid system secures communications using a dual-layer approach: QKD enables key transmission via quantum-mechanical principles, while PQC leverages hard mathematical [...]…

The world’s first commercial cryptographic system, immune to pirate attacks, including those with quantum computers, was recently introduced by the state-owned China Telecom Quantum Group, reported The South China Morning Post. As part of this advance the company also made the first transregional phone call with quantum encryption from the world at a distance of more than 1,000 kilometers between Beijing and the city of Hefei using this integrat…

[Digital Daily Reporter Chae Seong-oh] "When quantum computers are introduced, encryption systems will collapse, so we thought about what we should have as countermeasures for this. One of the defense areas is a solution related to quantum cryptography communication networks that combine quantum, encryption, and communication networks. We have introduced and are utilizing representative solutions, 'quantum key distribution (QKD)' and 'quantum-re…

The advance of quantum computing has put traditional encryption methods in check. While today we have robust systems, quantum computers promise to solve complex calculations with such a speed that they could break current cryptographic barriers in a matter of seconds. Faced with this scenario, China has taken a firm step: China Telecom Quantum Group has presented what it considers the first commercial cryptography system resistant to quantum com…
