Minimal Scenarios Witnessing Genuine Multipartite Nonlocality Possibilistically
The study investigates strong genuine multipartite nonlocality (GMNL) by constructing robust games, specifically a 5-party scenario. It shows that this scenario exhibits a strong form of pseudotelepathy, which is hard to achieve with fewer parties. This demonstrates that quantum mechanics requires the full multipartite structure to exhibit this specific type of nonlocal behavior.
