Popular Summary Quantum key distribution (QKD) enables two remote parties to establish a shared secret key even in the presence of an eavesdropper that has access to a quantum computer. The obtained key then can be used to encrypt secret messages. Continuous-variable QKD (CV-QKD) protocols with discrete modulation (DM) are promising candidates for commercial implementations because the required components are already used in current telecommunications infrastructure.
