Bell's inequality and the coincidence-time loophole
This paper analyzes effects of time-dependence in the Bell inequality.
A generalized inequality is derived for the case when coincidence and
non-coincidence [and hence whether or not a pair contributes to the
actual data] is controlled by timing that depends on the detector
settings. Needless to say, this inequality is violated by quantum
mechanics and could be violated by experimental data provided that the
loss of measurement pairs through failure of coincidence is small
enough, but the quantitative bound is more restrictive in this case
than in the previously analyzed ``efficiency loophole.''
