- No, he proved that some of the predictions of QM require that the
- outcome of a measurement must depend on a distant setting.

- This argument looks like a rather clever sleight of hand to me. The
- last statement requires a proof. While it's certainly true that one
- cannot use that equation to obtain an instantaneous change in the wave
- function at a given location due to a change in a distant polarizer
- angle, it's not at all obvious to me that you need this in order to
- describe what is happening. Maybe I'm missing something.
-
- I've already shown that the nonlocal dependence required by Eberhard's
- proof is implicitly contained in the rotational invariance of the
- singlet state. Thus the singlet state vector already knows how it will
- be affected by any possible combination of polarizer angles. I believe
- the effect can be described entirely in terms of local interactions.
- See my next post.
