The experiments don't have to involve particles. The experiments might be experiments in which theories are tested/implemented in which the word particle occurs. But they could also be experiments in which theories are tested/implemented in which there are only waves. It depends what the physicist puts inside (or rather: thinks he or she is putting inside) that big long box drawn in the figure from "Bertlmann". There is no particle drawn in the picture. There was no need whatever to use the word "particle" in the description of the experiment. There are three inputs and three outputs on a long box, and there is some time schedule which needs to be adhered to.TrickyDicky said:You seem to be missing my point, you are describing experiments that involve particles aren't you?
For instance, *inside* that long box one could place a network of three computers. The one in the middle sends some messages to the ones at each end, and also delivers an output saying "I did it". The ones at each end do some local computation based on their respective inputs and the message that came from the central computer.
What we very well understand, is that if we put three classical computers in the box, and do the experiment, the resulting statistics will satisfy the Bell-CHSH inequality. We imagine that if instead we put some quantum source and some quantum detectors inside the box and are really smart with our quantum engineering (creating some "particles" in a desired "state" and implementing certain "quantum measurements" on those "particles") then we would violate the Bell-CHSH inequality. (It hasn't been done yet, but maybe it will be done soon).
