Continuous‐Variable Quantum Key Distribution with Gaussian Modulation—The Theory of Practical Implementations
Abstract Quantum key distribution (QKD) using weak coherent states and homodyne detection is a promising candidate for practical quantum‐cryptographic implementations due to its compatibility with existing telecom equipment and high detection efficiencies. However, despite the actual simplicity of the protocol, the security analysis of this method is rather involved compared …
