How channel noise VE influences the security of CVQKD with (dashed line, gDLA=20 , gNLA v = 0.96) and without HLA (solid line) at f = 1 THz. The green, blue, and red line denote VE = 5, 12, 20 respectively. The attenuation is around 850 dB/km. A decrease in channel noise VE will enhance the performance of TS-CVQKD protocol rapidly.
