Chinese Microsatellite Successfully Transmits Unhackable Quantum Keys Over 12,000 Kilometers

A Chinese microsatellite has successfully transmitted unhackable quantum keys over a distance of 12,000 kilometers to a mobile ground station. This technological advancement demonstrates China's ability to use satellites for secure long-distance communications. The transmission of quantum keys ensures maximum security, as any attempt at interception would immediately disrupt the signal, alerting the involved parties. This achievement marks a significant milestone in the field of quantum cryptography and secure communications.
