Can we violate Bell inequalities by giving up CFD?

Click For Summary
SUMMARY

The discussion centers on the violation of Bell inequalities when counterfactual definiteness (CFD) is abandoned while maintaining locality. Participants argue that by accepting qubits instead of classical bits and rejecting realism, it is possible to achieve this violation through quantum mechanics (QM). The conversation references specific models and axioms, particularly emphasizing the role of observations in QM and the implications of locality and predictability. Key contributions include links to relevant papers and models that illustrate these concepts.

PREREQUISITES
  • Understanding of quantum mechanics (QM) principles, particularly entanglement and superposition.
  • Familiarity with Bell's theorem and Bell inequalities.
  • Knowledge of counterfactual definiteness (CFD) and its implications in quantum theory.
  • Basic comprehension of quantum measurement theory and the concept of POVMs (Positive Operator-Valued Measures).
NEXT STEPS
  • Research the implications of Bell's theorem in quantum mechanics.
  • Study the concept of superdeterminism and its relation to locality in quantum experiments.
  • Explore the mathematical formalism of quantum correlations and their interpretations.
  • Examine the role of POVMs in quantum measurement and their impact on outcomes.
USEFUL FOR

Quantum physicists, researchers in quantum information theory, and anyone interested in the philosophical implications of quantum mechanics and the nature of reality.

zonde - just call it physical realism :)
You are too radical. Physical realism allows probabilistic results just as well but we speak about CFD only in case of definite results.

No problem, I'd already deleted the comment when you replied :)
