We report our progress toward developing a parametric down conversion apparatus for studying single photon quantum optics in undergraduate laboratory classes, following the model of Galvez et al. . We pump a beta barium borate (BBO) crystal with a 405 nm diode laser to produce correlated pairs of single photons that we detect using avalanche photodiodes (APD). We can conduct coincidence and anticoincidence counts and a measurement of the degree of second-order coherence with the apparatus, and we report a g(2) < 1. We also discuss the headway towards developing a single-photon interferometer.
