In one experiment using this setup, a coincidence circuit makes sure that only particles produced through spontaneous parametric down-conversion are counted.
In one experiment using this setup, a coincidence circuit makes sure that only particles produced through spontaneous parametric down-conversion are counted. The half-silvered mirror in a device named for Mach and Zehnder produces a similar output as one of these setups. Wheeler's delayed choice experiment is meant to make sense of this apparatus. In the quantum eraser experiment, their output depends on whether or not the photon's path is observed. The distance between the fringes produced by this apparatus is inversely proportional to the distance between the two central entities, and its pattern is repeated in a diffraction grating. For 10 points, identify this setup which produced an interference pattern, demonstrating light's wavelike nature in a Thomas Young experiment.
