Holevo classicalisation and context integration: Global versus protocolwise integration
Jan van Neerven, Marijn Waaijer
Suppose that a family of commutative measurement contexts is given, together with the corresponding classical probability laws. We study the problem under what conditions these con…

We present an analysis of the Frauchiger-Renner Gedankenexperiment from the point of view of the relational interpretation of quantum mechanics. Our analysis shows that the paradox…
