No relation for Wigner's friend
arXiv:2011.08190 · doi:10.1007/s10773-021-04826-9
Abstract
We argue that Wigner's friend thought experiment does not support observer dependence of quantum states. An analysis in terms of history vectors suggests that quantum collapse is to be understood as collapse of histories rather than collapse of states.
