Detectability of Post-Quantum Correlations in Symmetry-Restricted Bell Scenarios
Marek Gazdzicki, Francesco Giacosa
Searches for post-quantum correlations depend on two distinct ingredients: how abundant such correlations are in the underlying correlation space and how efficiently the chosen rep…

From breakfast, lunch, and dinner to the Bell-inequality tetrahedron
Francesco Giacosa
A simple pedagogical discussion and visualization of certain Bell inequalities is presented with the help of a system involving two \textquotedblleft twins\textquotedblright, origi…

Symmetric Locality as a Tetrahedron: A Symmetry-Reduced Geometric Representation of the (3,3,2,2) Bell Scenario
Marek Gazdzicki, Francesco Giacosa, Pawel Piesowicz
We present a geometric characterisation of local models in the bipartite Bell scenario with three measurement settings per site and binary outcomes, i.e. the (3,3,2,2) case. Restri…
