Quantum key distribution (QKD) is a method used for secure or secret key exchanges between two remote users.

"Using secure communication, cyberscientists ultimately aim to establish a global quantum network," writes Thamarasee Jeewandara in Phy.org.

"Existing field tests suggest that such quantum networks are feasible. To achieve a practical quantum network, several challenges must be overcome including the realization of varied topologies at large scales, simple network maintenance and robustness to node failures. In a new report now published on Science Advances, Teng-Yun Chen and a research team in quantum physics, quantum information and interdisciplinary information sciences in China, presented a field operation of a quantum metropolitan area network with 46 nodes..."
