Every non-signalling channel is common-cause realizable
Paulo J. Cavalcanti, John H. Selby, Ana Belén Sainz
In this work we show that the set of non-signalling resources of a locally-tomographic generalised probabilistic theory (GPT), such as quantum and classical theory, coincides with…
Addressing some common objections to generalized noncontextuality
David Schmid, John H. Selby, Robert W. Spekkens
When should a given operational phenomenology be deemed to admit of a classical explanation? When it can be realized in a generalized-noncontextual ontological model. The case for…
Any consistent coupling between classical gravity and quantum matter is fundamentally irreversible
Thomas D. Galley, Flaminia Giacomini, John H. Selby
When gravity is sourced by a quantum system, there is tension between its role as the mediator of a fundamental interaction, which is expected to acquire nonclassical features, and…
