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…
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…
Post-quantum steering is a stronger-than-quantum resource for information processing
Paulo J. Cavalcanti, John H. Selby, Jamie Sikora +2
We present the first instance where post-quantum steering is a stronger-than-quantum resource for information processing -- remote state preparation. In addition, we show that the…
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…
