This question is about the justification for the CHSH assumption of indeterminate photons in the proof of spooky quantum entanglement.
CHSH assumes that the photons have indeterminate polarization with strange justification. It is generally agreed that one Barium borate oxide crystal (BBO) cannot produce photons that have indeterminate polarization. CHSH puts 2 BBOs together with one that produces vertically polarized photons and one that produces horizontally polarized photons and assumes that makes the photons indeterminate. That seems like saying, with one guy throwing tomatoes at an actor and when another guy starts throwing eggs, the tomatoes become half tomato and half egg. The CHSH experiments slow the generation of photon pairs from one BBO so that at least 25ns separates the pairs in time. That seems to make the state of the polarization known, not indeterminate. When one of the detectors is set to match vertical polarization, one of its counters registers vertical polarization and the other registers horizontal polarization so everything is known about the polarization of the photons and which BBO they came from. What is indeterminate in this experiment?
Addition: If there is nothing indeterminate, the CHSH experiments are worthless. How about answering the question?
Addition: The indeterminacy is a big loophole.
Another fatal mistake in the CHSH experiments is that Bell’s inequality would not violate without erroneously setting up the inequality.
It turns out that 3 of the 4 CHSH tests are really the same test. That means that they do not fit Bell’s Inequality test that CHSH uses to “prove” its case. Both quantum predictions and the physical tests show that the only angle the results depend on is the angle between the polarizers. CHSH uses the actual angles of the polarizers. When both polarizers are turned the same amount, that does not change the results. One of the tests usually has a difference of 67.5 degrees and the other 3 tests all have a difference of 22.5 degrees.
Bell’s Inequality is P(A,B) - P(A,B’) + P(A’,B) + P(A’,B’) >= 2.
CHSH would be P(A,B) - P(A,B’) + P(A,B) + P(A,B) which is certainly not the same.
The experiment does not violate Bell’s inequality or even test it.
