  Bases of exactly localized Minkowski and Rindler states on spacelike
hypersurfaces are used to describe inertial and accelerated photon counting
devices. It is found that the spacetime coordinates of photons absorbed by a
pair of counteraccelerating detectors in causally disconnected Rindler wedges
are correlated. If a photon is absorbed by a single accelerated detector the
Minkowski vacuum collapses to a state containing at least one photon and that
photon can be absorbed by an inertial detector.
