Fig. 3: Triple coincidence measurement.
From: Time-bin entangled Bell state generation and tomography on thin-film lithium niobate
a Two-dimensional coincidence histogram between signal, idler and pump trigger. Insets show coincidence counts relative to the pump clock on signal and idler channels independently. Drawn ellipses highlight the possible measurement outcomes and are colour-coded correspondingly to the peaks of the collapsed, one-dimensional histogram in (b). Labels in panel (b) explicitly mark which measurement outcome corresponds to each histogram peak, with the central one representing the interfering on-time state.
