They present the world's first cryptographic system immune to hackers

The company announced that it also made the world's first transregional phone call with quantum encryption over a distance of more than 1,000 km between Beijing and the city of Hefei using this integrated system. The state-owned China Telecom Quantum Group presented the world's first commercial cryptographic system that cannot be hacked even by quantum computers, according to The South China Morning Post.

The company announced that it also made the world's first transregional phone call with quantum encryption over a distance of more than 1,000 km between Beijing and the city of Hefei using this integrated system, RT reports.

The new system uses both quantum key distribution, which employs the principles of quantum mechanics to securely transmit encryption keys, and post-quantum cryptography, which is based on complex mathematical problems to secure data.$FUN
