Wigner-friend scenarios with noninvasive weak measurements
A. Matzkin, D. Sokolovski
Abstract
In this paper, the authors extend the ``Wigner friend'' scenario with two sets of laboratories to the case where the external agents can probe the laboratories in an asymptotically noninvasive manner, using weak measurements. The authors conclude that within their scheme (which allows a small coupling to the lab), the weak measurements indicate to the agents how to obtain consistent predictions.
