Computing results of the SSP instances where the set is {2, 3, 5, 7, 11, 13, 17} and {2, 5, 7, 11, 13, 17}, respectively. (a) and (c) The experimental read-out displays as a line of spots, which certify the existence of the corresponding subset sums (i.e., the numbers below the spots). (b) and (d) The experimental and theoretical intensity distribution. In the theoretical cases, nonzero intensity certifies the existence of a subset sum. By applying a reasonable intensity threshold, the experimental signals can be correctly classified into valid (beyond the threshold) and invalid certifications (below the threshold). The tolerance intervals of the thresholds are marked by the black bands.
