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…
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…
A decompositional framework for process theories in spacetime
Matthias Salzger, John H. Selby
There has been a recent surge of interest within the field of quantum foundations regarding incorporating ideas from general relativity and quantum gravity. However, many quantum i…
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…
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…
