Did rotating polarizer show violations of Bell's Inequality?

[PeterDonis]

Physical states may be represented mathematically as rays in Hilbert space, but the photons, in my opinion, remain in standard three-dimensional space, or if you wish, 4-dimensional spacetime.

Sorry, but you don't get to just use your opinion.

At this point you are verging on personal theory and therefore on receiving a warning. You don't get to just make up your own physics.

In the Aspect experiment, both photons have the same polarization as seen by detectors that are oriented in the same direction.

See the bolded qualifier, which is crucial.

With the qualifier, the statement is true, but this polarization is not restricted to one plane. The two detectors will always show the same polarization no matter which direction they are oriented, as long as the two detectors are both oriented in the same direction. The entangled photon state that produces these results is not at all the same as a two-photon state that is produced by restricting the polarization to one plane at the source. The latter state is not and cannot be an entangled state.

As for a sequence of entangled photons in one polarization plane, I cannot produce them, but I would be very surprised if they are never produced.

Then you should indeed be very surprised, because the argument I have already given for why they cannot be produced makes use of the same QM model of photons that, as I have said, already has a huge amount of experimental support. That's why nobody has produced such a state: because it's impossible, and everyone in the field knows it.
