*Fr.: inégalité de Bell*
Any of a large number of inequality relations developed to
study the → *hidden variable* hypothesis suggested in
the → *EPR paradox*. Using Bell's inequalities,
the → *Aspect experiment* showed that
no local hidden variable theory can make predictions in agreement with those of
quantum mechanics. If, in a measurement, the inequality is violated, the measurement
is in agreement with the predictions of the quantum theory. If the equality is
satisfied, it suggests that a classical, causal, and local model is adequate
to explain the outcome of the measurements.
