Abstract
We have measured the phase structure of a glass wedge with single photons and biphotons in a Mach–Zehnder interferometer using parametric downconverted light from a Hong–Ou–Mandel particle interferometer as the source. By scanning the wedge through the focus of a microscope objective we find a doubling of the period of the interference pattern in the coincidence counts for biphotons compared to the single-photon experiment. We compare our measurement setup with classical ones and discuss some of the problems of superresolution in quantum lithography.
