On May 7, 2026, a dedicated research team hailing from the University of Science and Technology of China achieved a remarkable feat by successfully constructing the "Xinghan-2" multi-mode quantum relay network in Hefei. This network enabled them to achieve matter entanglement over an impressive distance of 14.5 kilometers. This significant breakthrough is poised to serve as a cornerstone technological pathway for the quantum networks of the future. The team's related research findings were promptly published in the esteemed journal Nature Photonics on the very same day. Notably, this innovative approach effectively resolves the long-standing contradiction between quantum relay rate and fidelity. With an entanglement distribution rate that surpasses that of previous metropolitan-area quantum relays by more than a hundred times, it marks a substantial leap forward in the field.
