Typicality of Contextuality
Vinicius P. Rossi, Beata Zjawin, Roberto D. Baldijão +5
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…

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…

Robustness of contextuality under different types of noise as quantifiers for parity-oblivious multiplexing tasks
Amanda M. Fonseca, Vinicius P. Rossi, Roberto D. Baldijão +2
Generalised contextuality is the notion of nonclassicality powering up a myriad of quantum tasks, among which is the celebrated case of a two-party information processing task wher…
