Title: Pete Evans
A New Slant on the EPR-Bell Experiment
The best case for thinking that quantum mechanics is nonlocal rests on
Bell's Theorem, and later results of the same kind. However, the
correlations characteristic of EPR-Bell (EPRB) experiments also arise in
familiar cases elsewhere in QM, where the two measurements involved are
timelike rather than spacelike separated; and in which the correlations are
usually assumed to have a local causal explanation, requiring no
action-at-a-distance. It is interesting to ask how this is possible, in the
light of Bell's Theorem. We investigate this question, and present two
options. Either (i) the new cases are nonlocal, too, in which case
action-at-a-distance is more widespread in QM than has previously been
appreciated (and does not depend on entanglement, as usually construed); or
(ii) the means of avoiding action-at-a-distance in the new cases extends in
an obvious way to EPRB, removing action-at-a-distance in these cases, too.
There is a third option, viz., that the new cases are strongly disanalogous
to EPRB. But this option requires an argument, so far missing, that the
physical world breaks symmetries which otherwise support the analogy. In the
absence of such an argument, the orthodox combination of views -
action-at-a-distance in EPRB, but local causality in its timelike analogue -
is less well established than it is usually assumed to be
