# Nonlocality claims are inconsistent with Hilbert-space quantum mechanics

@article{Griffiths2020NonlocalityCA, title={Nonlocality claims are inconsistent with Hilbert-space quantum mechanics}, author={Robert B. Griffiths}, journal={Physical Review A}, year={2020} }

It is shown that when properly analyzed using principles consistent with the use of a Hilbert space to describe microscopic properties, quantum mechanics is a local theory: one system cannot influence another system with which it does not interact. Claims to the contrary based on quantum violations of Bell inequalities are shown to be incorrect. A specific example traces a violation of the CHSH Bell inequality in the case of a spin-3/2 particle to the noncommutation of certain quantum operators…

The violation of Bell inequalities and inconsistent connectedness may be explained using a contextual locally causal probabilistic model in which setting dependent variables describing measuring instruments are correctly incorporated and it is proved that this model does not restrict experimenters’ freedom of choice which is a prerequisite of science.
