Mini-Satellite Sends Encrypted Quantum Message a Record-Breaking Distance

Chinese scientists have broken a distance record in quantum communication, transmitting encrypted images nearly 13,000 km from China to South Africa using a lightweight microsatellite. The satellite, Jinan-1, sent laser pulses to create a quantum key for encrypting images. This achievement brings us closer to ultra-secure messaging between any two locations on Earth. The technology is more efficient and cost-effective than previous systems, paving the way for practical quantum key distribution networks globally.
