China, Russia claim to have tested hack-proof quantum communication link

"Scientists from Russia and China have allegedly achieved quantum communication encryption using secure keys transmitted by China's quantum satellite Mozi.

Quantum communication encryption uses the principles of quantum mechanics to establish secure communication channels.

It aims to create unbreakable encryption, making it highly attractive for applications where the highest level of security is essential, such as in transmitting sensitive information in fields like finance, government, and defense."

"This breakthrough demonstrates the technical feasibility of establishing a BRICS (Brazil, Russia, India, China, South Africa) quantum communication network.
The researchers managed to cover a distance of 3,800 kilometers between a ground station near Moscow and another close to Urumqi in China's Xinjiang region, transmitting two encoded images secured by quantum keys, reported the South China Morning Post."
