An Operational Analysis of Quantum Eraser and Delayed Choice Academic Article uri icon


  • In the present paper we expand upon ideas published some time ago in connection with which path detectors based on the micromaser. Frequently questions arise concerning the time ordering of detection and eraser events. We here show, by a detailed and careful analysis of a quantum eraser experimental setup, that the experimenter can choose to ascertain particle-like which path information or wavelike interference information even after the atom has hit the screen.
