(Color online) Comparisons of the final key generation rate between Xu et al.’s method and ours by applying the Chernoff bound analysis. (a) displays the absolute key generation rates with logarithmic coordinate, and (b) exhibits the relative values with linear scale. W1 (H1) represents the results of Xu et al.’s method, and W2 (H2) denotes ours. Here the number of pulses is reasonably set at N = 10¹¹.
