Implication

Randomized trial evaluates photon polarization correlations, revealing quantum mechanical predictions in local hidden-variable theories.

Key Points

  • The aim is to measure polarization correlations in photons to test local hidden-variable theories against quantum mechanics.
  • Measured linear polarization correlation of photons from a mercury cascade transition.
  • Evaluated Freedman's version of the Bell inequality using the results from polarization measurements.
  • Explicitly measured the initial density matrix of cascading atoms.
  • Measured experimental result, δ_exp = +0.046 ± 0.014, violating the Bell inequality.
  • Result aligned with quantum mechanical prediction, δ_QM = +0.044 ± 0.007.
