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…

The resource theory of causal influence and knowledge of causal influence

Marina Maciel Ansanelli, Beata Zjawin, David Schmid +5

Understanding and quantifying causal relationships between variables is essential for reasoning about the physical world. In this work, we develop a resource-theoretic framework to…

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…

Indistinguishability in general probabilistic theories

John H. Selby, Victoria J. Wright, Máté Farkas +2

The existence of indistinguishable quantum particles provides an explanation for various physical phenomena we observe in nature. We lay out a path for the study of indistinguishab…

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…
