What happens once an accelerating observer has detected a Rindler particle

In a seminal paper, Unruh and Wald found that the detection of a right Rindler particle by a linearly uniformly accelerated detector coupled to a free field in the Minkowski vacuum leads to the creation of a Minkowski particle from the inertial viewpoint. In this paper, we revisit the framework studied by Unruh and Wald, but now consider in addition what happens once the particle has been measured somewhere in the right Rindler wedge. We find that the such measurement induces changes to the expectation value of the stress-energy tensor in the left Rindler wedge, and opens the possibility for designing superluminal communication protocols between two spacelike separated observers confined to the right and left Rindler wedges respectively. We discuss the possible ways of avoiding such measurement-induced, faster-than-light signalling protocols, but it seems to us that the question remains open.
