Hi.
The Wikipedia article on the delayed choice quantum eraser is mostly about Kim's experiment where there's IMHO not really a 'choice' about the erasure of the path information, at least not by the experimentators. Have such experiments also been performed where this choice is more controllable, e.g. by mechanically inserting a beam splitter to make the idler photons indistinguishable (after the signal photon already hit the screen)?
If yes, how was this choice made? I guess all those experiments are faster than a human could press a button. But normal random number generators might present the same possibilities for loopholes as Bell test experiments.
