Local Realistic Model of Bell Theorem Experiment and Alternative Model   of Quantum Measurement
  A previous paper demonstrated that two local, realistic models based on Markov Random Fields (MRF) across space time do replicate the correct, tested predictions of quantum mechanics for simple Bell Theorem experiments. This paper demonstrates a third such model, MRF3, which is more plausible physically, making contact with the physics of polarizers. It shows how to translate that type of model into an equivalent quantum mechanical model, which requires an augmentation to the usual measurement operator now used to represent polarizers in such experiments. The validity of that augmentation may be testable in experiments involving three or four photons, with relevance to quantum computing and communication.
