- My point, such as it was, was that I would expect simple-minded classical
- predictions to also hold true for QM, because in the limit for large number
- of particles QM results in classical predictions. Especially for something
- simple-minded like a delay. I just don't think that we are going to see
- anything other than the simple t = d/c sort of delay come out of any
- experiment. The major place Maxwell's equations come into this simple
- formula is in any necessary adjustment of 'c' from the free-space value,
- BTW.
-
- In spite of the fact that QM requires one to do odd things like sum intergals
- over all possible paths (at least using the Feynman approach) the results
- ultimately match the classical ones as far as delays go, (at least if the
- paths are of macroscopic length) - even though the method of arriving at the
- result is a lot different.
-
- As far as classical equivalents to the Aspect experiment go, I'm not as
- sure as you are that something roughly analogous couldn't be thought up with
- a pair of polarized beams randomly (but identically) phase modulated, but I
- haven't really thought this through.
