Exploring Bell Nonlocality with Extremal Non-Signaling Boxes
Emmanuel Zambrini Cruzeiro, Junior R. Gonzales-Ureta, Raman Choudhary +3
Extremal non-signaling (ENS) boxes are correlations that correspond to vertices of the non-signaling polytope of a Bell scenario. Neither quantum theory nor any theory for ideal me…

Equivalence between face nonsignaling correlations, full nonlocality, all-versus-nothing proofs, and pseudotelepathy
Yuan Liu, Ho Yiu Chung, Emmanuel Zambrini Cruzeiro +3
We show that a quantum correlation is in a face of the nonsignaling polytope with no local points if and only if has nonlocal content 1, if and only if allows for a Gre…
