  • Fig. S6. Contour plot of distribution of pairs d(data, A), d(data, B) of variation distances between the output distribution associated with an incorrectly heralded event and either the hypothesis of correct heralded input (A) or the hypothesis of
    correct input but using distinguishable photons (B).
  • Fig. S7. Numerical simulation of a validation test of simulated experimental data against the hypotheses of correct boson sampling data (D > 0), and the hypothesis that photons are distinguishable (D < 0).
  • Fig. S8. Ratio R = Pdet no shutters / Pdet shutters between the per-pulse probability of detecting three photons in the trigger apparatus and three photons after the chip without shutters and with shutters, as a function of the number m of sources and modes (g = 0.1, ηT = 0.2, ηD = 0.015).
