Lumped Parameter Modeling of a Quantum Optics Circuit and Decisive Test for Time-Symmetric Physics
This paper showed how a simple lumped parameter model of a circuit can yield
correct quantum mechanical predictions of its behavior, even when there is
quantum entanglement between components of that circuit. It addresses an
important example, the circuit of the original Bell's Theorem experiments for
ideal polarizers. Correct predictions emerge from two alternative simple but
time-symmetric models based on classical Markov Random Field across space time.
Exact agreement here does not violate Bell's Theorem itself, because the
interplay between initial and final outcomes in these calculations does not
fall within the CHSH definition of time forwards causality. Both models raise
interesting questions for future research. The final section discusses several
possible directions for following up on these results, both in lumped system
modeling and in more general approaches. The final section proposed a new
experiment with three-photon entanglement which could tell us which is true,
local realistic MRF models and time-symmetric physics, or conventional
predictions assuming the usual collapse of the wave function. The appendix
worked out what the conventional predictions would be for the proposed
experiment, and also gives a simple master equation version of the collapse
assumption which does not involve metaphysical observers. Section A.4 gives the
prediction for the new models.Comment: 14ps, 3 figs, 56 eqs, 22 refs. Revision 5 added a new final section,
proposing a new experiment to decide between local realistic MRF models and
conventional quantum mechanics, and a new appendix. v6 gives the correct
prediction for time-symmetric physics for the all-angles triphoton
experiment, cites a more detailed derivation, and summarizes how to modify
QED to accommodate time-symmetr
