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…
Three-outcome multipartite Bell inequalities: applications to dimension witnessing and spin-nematic squeezing in many-body systems
Guillem Müller-Rigat, Albert Aloy, Maciej Lewenstein +2
We present a three-outcome Bell inequality which we show to be naturally suited to explore nonlocal correlations in many-body spin-1 systems or SU(3) models. In the specific, we de…
Deriving three-outcome permutationally invariant Bell inequalities
Albert Aloy, Guillem Müller-Rigat, Jordi Tura +1
We present strategies to derive Bell inequalities valid for systems composed of many three-level parties. This scenario is formalized by a Bell experiment with observers, each…
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…
Effects of Topological Boundary Conditions on Bell Nonlocality
Patrick Emonts, Mengyao Hu, Albert Aloy +1
Bell nonlocality is the resource that enables device-independent quantum information processing tasks. It is revealed through the violation of so-called Bell inequalities, indicati…
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…
