Chris,
An excellent summation of quantum light phenomena.
I'm merely a naive information systems analyst, but there are several subtly interesting aspects of Bell test experiments that may support a physically oscillating particle-wave state manifestation of matter.
In a simple grating test, 'photons' do not pass through holes placed too far apart. I think the simplest explanation for this is that it is the propagating wave state manifestation of matter that passes through multiple grating holes.
If the grating holes are considered to physically partition propagating waves containing element state 'information' dispersed throughout some expanse of spacetime, the seemingly separate waves passing through the grating can be considered as separated, independently directed wave-fronts still representing the singular, originally emitted wave. Dispersed through spacetime, they may even continue to be physically adjoined to the singular origin wave.
Each of the partitioned wave fronts can be individually detected as particles at varying points in spacetime: they will all continue to reflect the characteristic properties of the originally emitted wave.
I think this scenario supports an oscillating state manifestation of elements in which elements are originally emitted as propagating waves. At some characteristic interval they may manifest as a stationary, spinning massive particle. Terminal detection through material absorption of wave momentum produces a stationary particle manifestation.
While I may have overlooked something, I suggest this interpretation as the simplest, physical explanation for quantum entanglement.
A very interesting essay.
Sincerely,
Jim
