# The Notion of Locality in Relational Quantum Mechanics

@article{MartinDussaud2018TheNO, title={The Notion of Locality in Relational Quantum Mechanics}, author={Pierre Martin-Dussaud and Carlo Rovelli and Federico Zalamea}, journal={Foundations of Physics}, year={2018}, volume={49}, pages={96-106} }

The term ‘locality’ is used in different contexts with different meanings. There have been claims that relational quantum mechanics is local, but it is not clear then how it accounts for the effects that go under the usual name of quantum non-locality. The present article shows that the failure of ‘locality’ in the sense of Bell, once interpreted in the relational framework, reduces to the existence of a common cause in an indeterministic context. In particular, there is no need to appeal to a… Expand

It is shown that it is far from clear what a relativization of states to observers exactly achieves and in what sense such an approach really advances the authors' understanding of the peculiar features of quantum phenomena, and it is argued that the claim that RQM is able to preserve locality is at best dubious.

Abstract The apparent nonlocality of quantum theory has been a persistent concern. Einstein et al. (1935) and Bell (1964) emphasized the apparent nonlocality arising from entanglement correlations.… Expand
