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) Relationship between maximum transmission distance and secret key rate with the parameters’ analysis of LOCM in the finite-size scenario, where the exchanged number signals N = 1012. (a) Comparison of the performance between the eight-state protocol based on LOCM operation and the original eight-state protocol with parameters λ = 0.3 and τ = {0.25, 0.45, 0.65}. (b) Comparison of the performance between the eight-state protocol based on LOCM operation and the original eight-state protocol with parameters τ = 0.45 and λ = {0.1, 0.3, 0.5}. |
