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…
Noncontextuality inequalities for prepare-transform-measure scenarios
David Schmid, Roberto D. Baldijão, John H. Selby +2
We provide the first systematic technique for deriving witnesses of contextuality in prepare-transform-measure scenarios. More specifically, we show how linear quantifier eliminati…
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…
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…
Kirkwood-Dirac representations beyond quantum states (and their relation to noncontextuality)
David Schmid, Roberto D. Baldijão, Yìlè Yīng +2
Kirkwood-Dirac representations of quantum states are increasingly finding use in many areas within quantum theory. Usually, representations of this sort are only applied to provide…
