Overview

Randomized trial reveals quantum correlation reproduction in Bell experiments, suggesting classical models can mimic quantum phenomena.

Key Points

  • The aim is to construct a local hidden-variable model that can reproduce quantum correlations in Bell-type experiments.
  • Developed a stochastic two-channel detector model employing a shared classical phase λ uniformly distributed between 0 and 2π.
  • Utilized Malus-law detection probabilities with two independent binary channels per detector.
  • Analyzed correlation results derived from the encoding of outputs.
  • The CHSH parameter showed |S| = 2√2, exceeding the classical limit of 2, indicating a violation using normalized correlation.
  • The normalized Pearson correlation violated CHSH inequality (|S| = 2√2 > 2) without altering the physical model.
  • The current application of the CHSH test cannot differentiate between the entangled quantum sources and the proposed classical model.
