# Chinese scientists have made significant breakthroughs in the research of scalable quantum networks

On February 6th, reporters learned from the University of Science and Technology of China that Pan Jianwei, Wang Ye, Bao Xiaohui, Zhang Qiang, Wan Yong, and several industry experts have made significant breakthroughs in scalable quantum network research: they have constructed the basic module of a scalable quantum relay for the first time internationally, making long-distance quantum networks a realistic possibility; at the same time, they achieved 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 to over 100 kilometers. The related results were published on February 6th in the international academic journals "Nature" and "Science."
