Minimum quantum resources for strong non-locality
Samson Abramsky, Rui Soares Barbosa, Giovanni Carù +3
We analyse the minimum quantum resources needed to realise strong non-locality, as exemplified e.g. by the classical GHZ construction. It was already known that no two-qubit system…
Possibilities Determine the Combinatorial Structure of Probability Polytopes
Samson Abramsky, Rui Soares Barbosa, Kohei Kishida +2
We study the set of no-signalling empirical models on a measurement scenario, and show that the combinatorial structure of the no-signalling polytope is completely determined by th…
Contextuality, Cohomology and Paradox
Samson Abramsky, Rui Soares Barbosa, Kohei Kishida +2
Contextuality is a key feature of quantum mechanics that provides an important non-classical resource for quantum information and computation. Abramsky and Brandenburger used sheaf…
