Histograms of counts from SPAD1, which is gated on for 40 ns. The OS of the HSPS is opened for . Main figure: the heralded photon peak timed to arrive during switch open time (i.e., channel A opening is properly synchronized with the incoming heralded photons); true, background, and dark count contributions are clearly seen. Inset: the OS open time is set to miss the heralded photon peak, thus it is highly suppressed: the ratio of the integrals of the heralded photon peaks in these two configurations is .

(a) ONF and (b) versus the switching time . The linear fits (solid lines) of the data (points) are shown, together with 95% confidence bands (dashed curves).
