Decoupling local classicality from classical explainability: A noncontextual model for bilocal classical theory and a locally-classical but contextual theory
Sina Soltani, Marco Erba, David Schmid +1
We construct an ontological model for the theory known as bilocal classical theory doi.org/10.1103/PhysRevA.102.052216. To our knowledge, this is only the second time that an ontol…

Symmetry-induced failures of tomographic locality: Constructing foil theories by twirling
Daniel Centeno, Marco Erba, Thomas D. Galley +7
Tomographic locality is a principle commonly used in the program of finding axioms that pick out quantum theory within the landscape of possible theories. The principle asserts the…

Noncontextual ontological models of operational probabilistic theories
Sina Soltani, Marco Erba, David Schmid +1
An experiment or theory is classically explainable if it can be reproduced by some noncontextual ontological model. In this work, we adapt the notion of ontological models and gene…
