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…

A complete characterisation of All-versus-Nothing arguments for stabiliser states
Samson Abramsky, Rui Soares Barbosa, Giovanni Carù +1
An important class of contextuality arguments in quantum foundations are the All-versus-Nothing (AvN) proofs, generalising a construction originally due to Mermin. We present a gen…

On the Cohomology of Contextuality
Giovanni Carù
Recent work by Abramsky and Brandenburger used sheaf theory to give a mathematical formulation of non-locality and contextuality. By adopting this viewpoint, it has been possible t…
