By the way, I think that the three-photon GHZ experiment leads to a simpler example of quantum weirdness than Bell’s Theorem. I mentioned it in an earlier thread:
…
In the GHZ experiment, an H’/V’ test is performed on one photon.
If it is H’, the other photons will match each other if both are submitted to an H’/V’ test; but they will mismatch if both are submitted to an L/R test.
If it is V’, the other photons will mismatch each other if both are submitted to an H’/V’ test; but they will match if both are submitted to an L/R test.
Given these results, all 64 possible settings of the 6 “hidden” bits are impossible , no probabilistic argument is needed – all the probabilities must be zero.
