A no-go theorem on the nature of the gravitational field beyond quantum theory
Thomas D. Galley, Flaminia Giacomini, John H. Selby
Recently, table-top experiments involving massive quantum systems have been proposed to test the interface of quantum theory and gravity. In particular, the crucial point of the de…
Correlations constrained by composite measurements
John H. Selby, Ana Belén Sainz, Victor Magron +2
How to understand the set of correlations admissible in nature is one outstanding open problem in the core of the foundations of quantum theory. Here we take a complementary viewpo…
Unscrambling the omelette of causation and inference: The framework of causal-inferential theories
David Schmid, John H. Selby, Robert W. Spekkens
Using a process-theoretic formalism, we introduce the notion of a causal-inferential theory: a triple consisting of a theory of causal influences, a theory of inferences (of both t…
Revisiting dynamics of quantum causal structures -- when can causal order evolve?
John H. Selby, Ana Belén Sainz, Paweł Horodecki
Recently, there has been substantial interest in studying the dynamics of quantum theory beyond that of states, in particular, the dynamics of channels, measurements, and higher-or…
A structure theorem for generalized-noncontextual ontological models
David Schmid, John H. Selby, Matthew F. Pusey +1
It is useful to have a criterion for when the predictions of an operational theory should be considered classically explainable. Here we take the criterion to be that the theory ad…
