China's Jinan-1 Satellite Sets Record for Quantum Communication Distance
The microsatellite enables secure quantum key distribution over nearly 13,000 km, marking a step toward a global quantum internet and spurring international competition.
- The Jinan-1 satellite achieved a record-breaking quantum communication distance of 12,900 km, connecting ground stations in China and South Africa.
- Using quantum key distribution (QKD), researchers securely transmitted encrypted images, demonstrating the technology's potential for ultra-secure communication.
- The satellite's lightweight design, weighing just 23 kilograms, allows for scalable deployment, paving the way for a constellation-based quantum internet.
- China plans to launch additional quantum satellites for commercial applications by 2026, in collaboration with China Telecom.
- Europe and the United States are also advancing quantum satellite projects, with launches anticipated by 2026, highlighting growing global investment in quantum communication.
