Our scientists have made a major breakthrough in scalable quantum network research

Researchers including Pan Jianwei, Wang Ye, Bao Xiaohui, Zhang Qiang, and Wan Yong from the University of Science and Technology of China, along with multiple industry experts, have achieved a major breakthrough in scalable quantum network research: they have constructed the world’s first basic modules for scalable quantum repeaters, making long-distance quantum networks a practical possibility; at the same time, they have realized long-distance high-fidelity entanglement between single-atom nodes, and based on this, they have for the first time broken the transmission distance of device-independent quantum key distribution beyond 100 kilometers. The related results were published on February 6 in the international academic journals Nature and Science. (Cailian Press)
