Yep, this makes sense -- resolving A definitively should not affect B -- I just had an overly-general picture of the wavefunction collapse.

Here's what I think I've learned so far: There is no guarantee that the QM formalism for photons will tell us something that is physically real about an experiment, because the QM notion of a photon is a mathematical abstraction that does not automatically describe any given physical...

Thanks for the input. After quite a bit of googling around, I happened upon the Bialynicki-Birula first quantized wave function of the photon, and a paper that uses it to describe the time evolution of two entangled photons, but unfortunately not in the case of the EPR-like experiments. This...

I know it is standard. Can you confirm that if you didn't know if the two particles were in separate physical locations, and you performed a measurement of position, it would also destroy the entanglement with respect to spin? If that would not destroy the spin entanglement, then I guess there...

Why aren't they wave packets? How else would you represent the definite knowledge that the particles now exist in separate physical locations (without conducting a measurement)? Isn't there something fundamentally different between a system that you know to have physically separate states, vs...

I'm confused about a premise implicit in the standard QM model of entanglement, which seems logically inconsistent. I understand that entanglement arises when two or more particles interact in some way to become synchronized in their quantum states, which also must be indeterminate in terms...
