The following paper seems to misunderstand basic physics. And attributes what is essentially classical Newtonian physics to imaginary pseudoscientific quantum effects.

This misunderstanding is based on the fact that QT theorists have assumed light is a particle *and* a wave. This is a false assumption. Light is wave only. And all imaginary magical “ quantum” effects are actually just theorists misunderstanding the wave based nature of light and pretending it’s also a particle. Any imaginary quantum effects can be just as well described by classical waves and classical polarisation. As the following links explain.

Take for instance the polarisation of EMR after reflection. Notice the handedness of the incident circular polarised wave changes handedness. But only in its direction of propagation!
Because from the observers point of view the incident wave has the same handedness as the reflected wave.
This is because polarisation of light is dictated by the angle of the magnetic field of the incident light wave. And thus the handedness of the polarisation of the reflected light will be the same as the angle of the incident light waves.
In case this doesn’t make sense to any student of physics indoctrinated into the nonsense of ridiculous quantum theory then look at how polarisation of a reflected wave depends on the polarisation of the incident wave.
If for an observer looking at the reflection plane at t_0 the incident circular polarised wave is polarised vertically relative to the observer at 12:00 o’clock. Then its reflected wave will also be polarised vertically. In other words the polarisation angle of the light beam moving towards and hitting the mirror will be vertical,relative to the observer.
Then it follows that at t_1 the incident circularly polarised wave has rotated slightly clockwise to 1:00 o’clock and that the reflected wave now moving towards the observer will also be polarised to the angle of 1:00 o’clock. BUT...relative to the observer.
This is referred to in physics as a flipping of handedness for polarisation at reflection. But what the reference fails to mention is that yes although the handedness flips at reflection. That is only true in the direction of propagation. Whereas from an observer point of view the handedness does not flip at reflection.
This phenomena also can explain the observations in the experiment cited above. Because the handedness of the magnetic fields of the atoms upon reflection at the barrier is dependent on the angle of the atoms magnetic field before it reflects. And notice in the experiment the handedness of the magnetic field of the atom after reflection is the same as before it is reflected. As with EMR at reflection.
No quantum effects needed. Just a simple following of the classical physics rule of magnetism on reflection.
Which is: From an external observers point of view looking at the mirror, if a magnetic field is reflected its angle of polarisation must be preserved. And, for the external observer, be the same for the reflected atom or light wave as the angle of polarisation of the incident atom or lightwave.
