Contextual advantage implies limited distinguishability in any physical theory
Roberto D. Baldijão, Felipe A. Barretto, Jarosław K. Korbicz
A central question in quantum information is whether a given set of states can provide an advantage in some information-processing task. We establish a universal connection between…
How Quantum Contextuality disappears in the Classical Limit
Arthur C. R. Dutra, Roberto D. Baldijão, Marcelo Terra Cunha
The emergence of classicality is fundamentally driven by the interaction between a quantum system and its environment. Foundational open-system approaches, notably the Caldeira-Leg…
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…
Typicality of Contextuality
Vinicius P. Rossi, Beata Zjawin, Roberto D. Baldijão +3
Identifying when observed statistics cannot be explained by any reasonable classical model is a central problem in quantum foundations. A principled and universally applicable appr…
A structure theorem for complex-valued quasiprobability representations of physical theories
Rafael Wagner, Roberto D. Baldijão, Matthias Salzger +3
Quasiprobability representations are well-established tools in quantum information science, with applications ranging from the classical simulability of quantum computation to quan…
Shadows and subsystems of generalized probabilistic theories: when tomographic incompleteness is not a loophole for contextuality proofs
David Schmid, John H. Selby, Vinicius P. Rossi +2
It is commonly believed that failures of tomographic completeness undermine assessments of nonclassicality in noncontextuality experiments. In this work, we study how such failures…
