Accessible fragments of generalized probabilistic theories, cone equivalence, and applications to witnessing nonclassicality
John H. Selby, David Schmid, Elie Wolfe +3
The formalism of generalized probabilistic theories (GPTs) was originally developed as a way to characterize the landscape of conceivable physical theories. Thus, the GPT describin…
Why interference phenomena do not capture the essence of quantum theory
Lorenzo Catani, Matthew Leifer, David Schmid +1
Quantum interference phenomena are widely viewed as posing a challenge to the classical worldview. Feynman even went so far as to proclaim that they are the only mystery and the ba…
Quantifying EPR: the resource theory of nonclassicality of common-cause assemblages
Beata Zjawin, David Schmid, Matty J. Hoban +1
Einstein-Podolsky-Rosen (EPR) steering is often (implicitly or explicitly) taken to be evidence for spooky action-at-a-distance. An alternative perspective on steering is that Alic…
Contextuality without incompatibility
John H. Selby, David Schmid, Elie Wolfe +3
The existence of incompatible measurements is often believed to be a feature of quantum theory which signals its inconsistency with any classical worldview. To prove the failure of…
Uniqueness of noncontextual models for stabilizer subtheories
David Schmid, Haoxing Du, John H. Selby +1
We give a complete characterization of the (non)classicality of all stabilizer subtheories. First, we prove that there is a unique nonnegative and diagram-preserving quasiprobabili…
