Question about the shift of patterns in the Delayed Choice Quantum Eraser

In the double-slit Delayed Choice Quantum Eraser experiment by Scully with the installation in the figure below, as in Wikipedia, when a photon hits D4 or D3 the intricated photon hits D0 with a ...

When does the exchange of energy take place in the Quantum Eraser experiment?

I found this PBS video regarding the delayed choice / quantum eraser experiment, which, like all the others I've seen, states that the interference pattern generated by the photons that pass through a ...

Has the Double-Slit Quantum Eraser Experiment ever been tried on a large scale?

I was just reading about quantum entanglement and the example was the Double-Slit Quantum Eraser Experiment. Then this was used as a basis for saying that particles might be half a universe apart and ...

What happens if you put the BBO before the slits in a delayed choice quantum eraser experiment?

I've read that you can't detect an interference pattern at D0 in the image below without correlating with data from D1, D2, D3, and D4 due to the coherence being broken by the BBO crystal. Does this ...

In delayed choice experiment, entangled photon was detected at D0. Why a single entangled photon can have interference data?

I am new here and also physics. i tried to understand the experiment more. In the following youtube video. the demonstration indicated that an entangled photon arrived at D0 while its partner arrived ...

Does this experiment on wave-particle duality and complementarity disprove quantum mechanics and prove the EPR viewpoint on it?

I recently read Photons act like they go through two paths, even when we know which they took, at Ars Technica, which reports on the paper Wave-particle dualism and complementarity unraveled by ...
