(color online) Number of exchanged signals and secret key rate in the case of heterodyne detection, where V_A = 0.25, η = 0.6, υ_el = 0.05, β = 0.95, and the two parameters of LOCM are λ = 0.3 and τ = 0.45. Solid curves mean the original eight-state protocol, and the dashed curves represent the scenario with an LOCM.
