Objective Wave Function and Non-locality

Click For Summary
SUMMARY

The discussion centers on the concept of non-locality in quantum mechanics, specifically comparing the Many Worlds interpretation and the Copenhagen interpretation with objective wave function collapse. It is established that all interpretations of quantum mechanics exhibit "true non-locality" as defined by the violation of Bell inequalities, which is an experimental fact. The conversation also addresses the necessity of statistical measurements to demonstrate these violations, emphasizing that direct correlations cannot be solely relied upon to validate non-locality without extensive data collection.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly wave function interpretations.
  • Familiarity with Bell inequalities and their significance in quantum experiments.
  • Knowledge of statistical methods in experimental physics.
  • Basic grasp of entanglement and its implications in quantum correlations.
NEXT STEPS
  • Study the implications of Bell's theorem on quantum interpretations.
  • Explore the Many Worlds interpretation and its stance on non-locality.
  • Investigate statistical methods used in quantum experiments to validate non-locality.
  • Read the GHZ paper on non-locality and its experimental setups.
USEFUL FOR

Quantum physicists, students of quantum mechanics, and researchers interested in the philosophical implications of non-locality and the interpretations of quantum theory.

for very small scale. One automatically needs relativistic quantum theory?

Yes, because to probe small scales experimentally you need high energy particles, i.e., relativistic particles (particles whose total energy is much higher than their rest energy).

Yes. This is if the probes are electrons or ordinary particles. But in beyond the standard model such as Nikolic's (and Wen's?) fundamental particles in condense matter analogy. It doesn't necessarily mean high energy particles were required to probe them? At least just wanting to know in principle if in beyond standard model. It is possible to have very small particles at small scale that doesn't require high energy probes (non-ordinary particles). If it's more appropriate to response this in the BSM forum. Then better because I want to know the answer to this.

What else can we probe with?

Discussions of such speculative hypotheses belong in the same forum as the other thread you linked to: the Beyond the Standard Model forum. Not this one.
