Quantum key distribution (QKD) can be proved to be secure by laws of quantum mechanics. Continuous-variable (CV) protocols attract a lot of interests since they use similar devices as the classical telecommunication method and thus can be a cost-effective solution to quantum-safe cryptography. In this talk, we discuss the asymptotic security of CVQKD with a discrete modulation. We will start with a discussion about a numerical method to calculate the secret key rate and then discuss advantages of CVQKD and discrete modulation. Finally, we will discuss how to formulate the optimization problem for this protocol.
