We report a quantum eraser experiment which actually uses a Young double slit to create interference. The experiment can be considered an optical analogy of an experiment proposed by Scully, Englert, and Walther [Nature (London) 351, 111 (1991)]. One photon of an entangled pair is incident on a Young double slit of appropriate dimensions to create an interference pattern in a distant detection region. Quarter-wave plates, oriented so that their fast axes are orthogonal, are placed in front of each slit to serve as which-path markers. The quarter-wave plates mark the polarization of the interfering photon and thus destroy the interference pattern. To recover interference, we measure the polarization of the other entangled photon. In addition, we perform the experiment under ``delayed erasure'' circumstances.

- Delayed-choice gedanken experiments and their realizations (2014, background): “In the experiment of Walborn et al. (2002), one photon of a polarization-entangled pair impinged on a special double-slit device, where two quarter-wave plates, oriented such that their fast axes are orthogonal, were placed in front of each slit to serve as which-path markers.”
