Minimal Scenarios Witnessing Genuine Multipartite Nonlocality Possibilistically
Soumyadip Patra, Peter Bierhorst
We study a strong form of genuine multipartite nonlocality (GMNL), where an -partite scenario admits a quantum strategy generating outcomes belonging to a restricted set with ce…

Quantum Advantage over Wirings of Nonsignaling Boxes in Multipartite Networks
Peter Bierhorst, Arkaprabha Ghosal, Soumyadip Patra
Quantum-entangled measurements are known to enable multi-party behaviors that are impossible with unentangled measurements on nonlocal resources, even those that are super-quantum…

Intractability of Witnessing Entangled Measurements Device Independently
Peter Bierhorst
Protocols have been previously proposed to certify the presence of an entangled measurement in a fully device-independent manner. Here, I provide models for these protocols in whic…
