Foreign media reported that a state-owned enterprise in China recently launched the world's first commercial encryption system claimed to be unbreakable by quantum computers. China Telecom Quantum Group announced the launch of the world's first distributed encryption system, which integrates two key technologies. By using this integrated system, the world's first trans-regional quantum-encrypted telephone call was successfully completed, covering a distance of more than 1,000 kilometers (600 miles), connecting Beijing and Hefei. With the rapid development of quantum computing technology, traditional cybersecurity frameworks are facing unprecedented challenges, as new algorithms increase the possibility of cracking traditional encryption systems. This new system combines two technologies: Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC). The former uses principles of quantum mechanics to securely transmit encryption keys, while the latter relies on complex mathematical problems to lock data. China Telecom stated that this system builds an end-to-end quantum security architecture applicable to core applications such as real-time communication, data protection, and trusted identity authentication. Peng Chengzhi, China Telecom's chief quantum scientist, said that with the global advancement of quantum computing, public-key-based encryption systems will face increasing threats.
