The relationship between parameter g and the mutual information. Solid red line denotes the mutual information between Alice and Bob S(A : B). Large dashed black line denotes the information eavesdropped by Eve S(B : E). Small dashed blue line denotes the secret key rate K. The modulation variance V is 10, the reconciliation efficiency is 0.95, and the channel loss is 0.8 dB. The ω₁ and ω₂ are set as 1.1.
