We obtain the experimental results of CHSH inequality and analog CHSH inequality as ScHsa=2.64±0.02 and SnalogCgS=2.76±0.02, respectively, and prove that the analog CHSH inequality is more robust against bit-flip noise than the CHSH inequality. It provides better advantages for the experimental study and application.展开更多
