    • Our approach, therefore, is quite different from the early “squeezed state” studies, e.g., 89, where the signal and idler radiation of SPDC are shown to be in the thermal (and hence mixed) state based on a single-mode model which allows all number states. Entanglement, however, was not described in those studies.

    • It is interesting to notice that apparently the same result, a triangular correlation function, was also obtained in a two-photon interference experiment 16 based on joint coincidence detections. The two experiments are fundamentally different: the earlier one 16 demonstrates the overlap of two biphoton amplitudes while the present reveals the shape of a single-photon wave packet. Even though we understand, mathematically, why the results are identical, the physical meaning of this fact remains puzzling.
