Finite-size analysis of eight-state continuous-variable quantum key distribution with the linear optics cloning machine Project supported by the National Natural Science Foundation of China (Grant Nos. 61379153 and 61572529). |
(color online) Numerical analysis of secret key rates based on the comparison between the LOCM-CVQKD protocol and the OA protocol, where VA = 0.25, η = 0.6, υel = 0.05, β = 0.95, the two parameters of LOCM are λ = 0.3 and τ = 0.45, and the parameter g = 20. Solid curves mean the OA eight-state protocol, and the dashed curves represent the scenario with an LOCM. |
