Tomographically-nonlocal entanglement
Roberto D. Baldijão, Marco Erba, David Schmid +2
Entanglement is a central and subtle feature of quantum theory, whose structure and operational behavior can change dramatically when additional physical constraints, such as symme…
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…
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…
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…
