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 debate …
A well-motivated method for demonstrating that an experiment resists any classical explanation is to show that its statistics violate generalized noncontextuality. We here …
We prove that given any two general probabilistic theories (GPTs) the following are equivalent:(i) each theory is nonclassical, meaning that neither of their state spaces is a …
The formalism of generalized probabilistic theories (GPTs) was originally developed as a way to characterize the landscape of conceivable physical theories. Thus, the GPT …

Resource theories provide a general framework for the characterization of properties of physical systems in quantum mechanics and beyond. Here we introduce methods for the …
The phenomenon of data hiding, ie the existence of pairs of states of a bipartite system that are perfectly distinguishable via general entangled measurements yet almost …
We solve a long-standing conjecture by Barker, proving that the minimal and maximal tensor products of two finite-dimensional proper cones coincide if and only if one of the two cones …
