Nonlocality, Integrability and Quantum Chaos in the Spectrum of Bell Operators
Albert Aloy, Guillem Müller-Rigat, Maciej Lewenstein +2
We introduce a permutationally invariant multipartite Bell inequality for many-body three-level systems and use it to investigate a connection between Bell nonlocality and (lack of…

Theory-independent monitoring of the decoherence of a superconducting qubit with generalized contextuality
Albert Aloy, Matteo Fadel, Thomas D. Galley +2
Characterizing the nonclassicality of quantum systems under minimal assumptions is an important challenge for quantum foundations and technology. Here we introduce a theory-indepen…

Spin-bounded correlations: rotation boxes within and beyond quantum theory
Albert Aloy, Thomas D. Galley, Caroline L. Jones +2
How can detector click probabilities respond to spatial rotations around a fixed axis, in any possible physical theory? Here, we give a thorough mathematical analysis of this quest…
