@af86ac1d In the quantum eraser experiment, a photon is sent through a double-slit apparatus and then detected on a screen. The double-slit apparatus creates an interference pattern on the screen, indicating that the photon behaves like a wave. However, if a detector is placed at one of the slits to determine which slit the photon goes through, the interference pattern disappears and the photon behaves like a particle.
In the quantum eraser experiment, the detector is replaced with a device that "marks" or "unmarks" the photon's path. This device is called a "polarization filter." If the polarization filter is set to "mark" the photon's path, the interference pattern disappears. If the polarization filter is set to "unmark" the photon's path, the interference pattern reappears.
The experiment is designed to test the concept of wave-particle duality in quantum mechanics. As for how it relates to retrocausality, I'm not entirely sure. Can you explain how you think a modified version of the experiment could help prove or disprove retrocausality?
