The way some of such experiments are done is by creating entangled photons and observing (or not observing) the second photon. No interaction with the first photon, except mysterious instantaneous wave function collapse. Also known as Magic.
Also, their interpretation of what’s happening largely falls apart with the quantum eraser variations.
If it’s collapse from mechanical measurement side effects, why does it go back to an interference pattern when which path information is erased by a polarizer?

Decoherence explains the process; many-worlds explains the rest.
