Comment on Frauchiger and Renner paper (Nat. Commun. 9, 3711 (2018)): the problem of stopping times
@article{Lerner2019CommentOF, title={Comment on Frauchiger and Renner paper (Nat. Commun. 9, 3711 (2018)): the problem of stopping times}, author={Peter B. Lerner}, journal={arXiv: Quantum Physics}, year={2019} }
The Gedankenexperiment advanced by Frauchiger and Renner in their Nature paper is based on an implicit assumption that one can synchronize stochastic measurement intervals between two non-interacting systems. This hypothesis, the author demonstrates, is equivalent to the complete entanglement of these systems. Consequently, Frauchiger and Renner's postulate Q is too broad and, in general, meaningless. Accurate reformulation of the postulate, Q1 does not seem to entail any paradoxes with…

This framework shows that the agents' claims become consistent if the changes in their memories are properly taken into account, and can be used to build a consistent scenario for the recently proposed extended versions of the Wigner's-friend experiment.
