In a major leap toward the development of a global quantum internet, researchers have successfully demonstrated real-time quantum key distribution (QKD) between a microsatellite and multiple mobile ground stations. The breakthrough, achieved with Jinan-1, the world’s first quantum microsatellite, was led by a research team from the University of Science and Technology of China (USTC) in collaboration with the Jinan Institute of Quantum Technology, Shanghai Institute of Technical Physics, the Chinese Academy of Sciences, and Stellenbosch University in South Africa. The findings were recently published in Nature. By enabling highly secure, unbreakable encryption, quantum communication is seen as the future...
