SUMMARY
This discussion centers on the perceived contradiction in the non-locality principle as it relates to polarization-entangled photons A and B measured by Alice and Bob. The key point is that while there is a correlation between the measurements of the two photons, the actual polarization states are not defined until measurement occurs. The conversation highlights that the measurement of one photon does not determine the state of the other, and relativity does not influence the causal relationship between the measurements. Ultimately, the discussion emphasizes that the wave function collapse occurs upon interaction with a macroscopic object, such as a polarizing filter, rather than being a direct result of one photon influencing the other.
