Now I understand what you wanted to say: The initial state ##|\psi\rangle## for the EPR experiment can be assumed to be ψ... I guess...

Maybe read what you wrote exactly, see whether it makes any sense to you. And then ask yourself, how anybody who wants to have a serious...

OK, what has this to do with my question, or with anything you wrote in your answer? Even in 1D, it makes an important difference...

The issue is that your answer doesn't help me to see how the entangled particles can be used for Bell's inequality violations. What do...

If you look at the actual combined state of the two subsystem that may be entangled, then you often end up with a density matrix instead...

Doesn't this depend on which degrees of freedom you use? If you choose two random photons and ignore all but their polarizations, they...

The effect is explained in the paper by quantum indistinguishability. But indistinguishability in QM is implemented by symmetrization of...

Also note that even the QED vacuum, i.e., a state with zero number of photons, is highly entangled. Hence it is really impossible to...
