| Classicality
and locality in Bell's
inequalities
|
Bell's
inequalities can be understood in
three different ways depending on
whether the numbers featuring in
the inequalities are interpreted
as classical probabilities,
classical conditional
probabilities, or quantum
probabilities. In the talk I will
argue that the violation of Bell's
inequalities has different
meanings in the three cases. In
the first case it rules out the
interpretation of certain numbers
as probabilities of classical
events. In the second case it
rules out a common causal
explanation of conditional
correlations of certain events
(measurement outcomes) conditioned
on other events (measurement
settings). Finally, in the third
case the violation of Bell's
inequalities neither rules out the
interpretation of these numbers as
probabilities of events nor a
common causal explanation of the
correlations between these
events---provided both the events
and the common causes are
interpreted non-classically.
