This one is especially delicious:
http://arxiv.org/abs/quant-ph/0007009
since
<Entangled photons are sent via an optical fiber network to two
villages near Geneva, separated by more than 10 km where they are
analyzed by
interferometers. The photon pair source is set as precisely as possible
in the center so that
the two photons arrive at the detectors within a time interval of less
than 5 ps
(corresponding to a path length difference of less than 1 mm). One
detector is set in motion
so that both detectors, each in its own inertial reference frame, are
first to do the
measurement! The data always reproduces the quantum correlations,
making it thus more
difficult to consider the projection postulate as a compact description
of real collapses of the
wave-function. >
What fun! Each photon does its utterly uncaused thing *first*, entraining
the other...
