# Violation of the Bell-CHSH inequality and marginal laws in a single-entity Bell-test experiment

@article{Aerts2019ViolationOT, title={Violation of the Bell-CHSH inequality and marginal laws in a single-entity Bell-test experiment}, author={Diederik Aerts and Massimiliano Sassoli de Bianchi}, journal={arXiv: Quantum Physics}, year={2019} }

We describe a simple experimental setting where joint measurements performed on a single (classical or quantum) entity can violate both the Bell-CHSH inequality and the marginal laws (also called no-signaling conditions). Once emitted by a source, the entity propagates within the space of Alice's and Bob's detection screens, with the measurements' outcomes corresponding to the entity being absorbed or not absorbed in a given time interval. The violation of the marginal laws results from the… Expand

An upper limit for the observed correlations is derived when Alice's and Bob's measurements are compatible, and Tsirelson's bound limits the quantum correlations in the Bell-CHSH inequality to $2\sqrt{2}$. Expand

This work demonstrates that to overcome the Bell bound, this correlation must be accompanied by the entanglement between the constituent particles and reveals a fundamental relation between the non-locality and the particleEntanglement. Expand

The phenomenon of entanglement in bipartite systems is provided, as it manifests in micro and macro physical systems, as well as in human cognitive processes, by observing that when genuine coincidence measurements are considered, the violation of the ‘marginal laws’ is to be expected. Expand
