Dhaka, Feb. 6 -- Scientists at the University of Science and Technology of China (USTC) have made major advances in scalable quantum networks, bringing the technology closer to real-world use. Their findings have been published in Nature and Science.

Quantum information science aims to create highly efficient and ultra-secure networks, which require the long-distance distribution of quantum entanglement - a phenomenon where particles share a unique connection.

This entanglement is vital for secure quantum communication and linking future quantum computers. A major hurdle has been signal loss in optical fibers, where transmission efficiency drops sharply with distance, making large-scale networks difficult to implement.

To overcome this...
