- Abstract: Bell-type inequalities allow for experimental testing of local hidden
variable theories. In the present work we show the violation of Mermin's
inequalities in IBM's five-qubit quantum computers, ruling out the local
realism hypothesis in quantum mechanics. Furthermore, our numerical results
show significant improvement with respect to previous implementations. The
circuit implementation of these inequalities is also proposed as a way of
assessing the reliability of different quantum computers.

Machine learning inspired variational methods provide a promising route towards scalable state characterization for quantum simulators.
We benchmark and compare several such approaches by applying them to measured data from an experiment producing two-qubit entangled states.
We find that in the presence of experimental imperfections and noise, confining the variational manifold to physical states greatly improves the quality of the reconstructed states.

Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality.
This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment.
It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
