Assuming nonlocal realism: What message would signal convey?

Click For Summary
SUMMARY

The discussion centers on the implications of Bell's inequalities and the nature of quantum mechanics (QM) in relation to nonlocal realism. Participants explore the necessity of instantaneous signaling between entangled particles, specifically polarized photons, and the concept of predetermined measurement outcomes. They debate the interpretations of realism and non-realism in quantum theory, highlighting the complexities of measurement parameters and hidden variables. The conversation concludes that both local non-realistic and non-local realistic interpretations have their merits and challenges, emphasizing the ongoing debate in the field of quantum mechanics.

PREREQUISITES
  • Understanding of Bell's inequalities and their implications in quantum mechanics.
  • Familiarity with quantum entanglement, particularly in the context of polarized photons.
  • Knowledge of measurement theory and the role of measurement devices in quantum experiments.
  • Concepts of realism and non-realism as they pertain to interpretations of quantum mechanics.
NEXT STEPS
  • Research the implications of Bell's theorem on local realism and non-local realism.
  • Study the role of hidden variables in quantum mechanics and their interpretations.
  • Explore the concept of contextuality in quantum theory and its relation to measurement outcomes.
  • Investigate Bohmian Mechanics as a non-local realistic theory and its criticisms.
USEFUL FOR

Quantum physicists, researchers in quantum mechanics, and students seeking to understand the philosophical implications of quantum theory and the debate surrounding realism and non-realism.

Why would that be significant to the physics in this case?
I consider that a legitimate question. I am not allowed to respond to that for I haven't got a rigorous theory about it, and probably never will have.

Seems like that would be common to any experiment ever.
I was aiming at measurements on entangled systems.
