Quantum Key Distribution (QKD) enables information-theoretic secure communication based on quantum physics. A new study by Danish, Austrian, and Canadian researchers has demonstrated composable secure key generation against collective attacks over 20 km fiber using discrete-modulated Continuous-Variable QKD and modern numerical security proof methods. This marks the first practical implementation of a long-theorized protocol, combining high key rates, standard telecom compatibility, and rigorous security guarantees - an important step toward real-world quantum-secure communication in metropolitan networks.
