Inadequacy of the CHSH Bell inequality for an application to the photon correlation experiments of Aspect et al
Résumé
We explain that the CHSH Bell inequality cannot be applied to the photon correlation experiments of Aspect {\em et al.} In fact, when we apply the inequality to
these experiments its derivation would imply that a single photon can have two different linear polarization states at the same time, while they cannot be measured at the same time. The issue is a consequence of the special experimental context we try to impose the
mathematics on. We are able to pinpoint the exact place in the derivation of the
inequality where the application of the mathematics to the physics causes a problem.
We then derive a Bell inequality that is appropriate for an application to the experiments.
The boundaries of this corrected inequality are much less stringent and the experiments do not violate this inequality.
