💻 As #QuantumComputers evolve, traditional #encryption methods become increasingly vulnerable. To counter this, researchers are developing quantum key distribution (QKD), a technology that uses #quantum physics to protect transmitted information. Fei Ding and team from Leibniz Universität Hannover successfully conducted the first intercity QKD experiment using a deterministic single-#photon source. This innovation brings us closer to secure quantum communication networks, enhancing protection a
