A major Chinese telecom company has launched what it claims is the first commercial security system that can protect digital communication from even the most powerful future hackers — including those using quantum computers.
China Telecom Quantum, a state-owned firm, recently introduced a new kind of encryption system that combines two advanced technologies to create strong protection for data, phone calls, and user identity. This system was successfully used to make a secure phone call between Beijing and Hefei a distance of more than 1,000 kilometers — without risking any data leaks or breaches.
The Problem: Quantum Computers Could Break Today’s Encryption
As quantum computing continues to develop, it is expected to pose a serious threat to current cybersecurity systems. These new types of computers are extremely fast and powerful, and experts believe they could one day crack the encryption used to protect sensitive information like passwords, bank data, and government records.
To stay ahead of these threats, China Telecom has built a new system that combines:
1. A quantum-based method that sends encryption keys using the principles of quantum physics, making them nearly impossible to steal or intercept.
2. A mathematics-based method that protects data using very difficult equations that even quantum computers would find hard to solve.
This two-layer approach forms a highly secure framework to protect digital communication.
Tested in Real Conditions and Ready to Use
China Telecom says the system has been tested successfully and is ready to be used on a large scale. The company has already created secure quantum networks in 16 cities, including Beijing, Shanghai, Guangzhou, and Hefei.
These networks now make up a nationwide secure communication system. Among them, Hefei’s network is the largest and most advanced in the world, with eight main hubs and over 150 connection points spread across 1,147 kilometers. It is already being used by around 500 government departments and nearly 400 publicly owned companies.
Extra Tools for Safe Messaging and Document Management
The company has also introduced two new secure tools:
• Quantum Secret — a messaging and teamwork app designed to keep communication safe from even advanced hackers.
• Quantum Cloud Seal — a platform made for secure digital approvals, auditing, and managing documents for businesses and government offices.
Both tools are already being used across different industries in China.
With this launch, China has taken a major step toward building a future-ready cybersecurity system — one that can stay strong even as quantum computing technology continues to grow.
