Bancal JD Branciard C Gisin N Pironio S 2009 The nonlocal correlations of multipartite entangled states can be reproduced by a classical model if sufficiently many parties join together or if sufficiently many parties broadcast their measurement inputs. The maximal number m of groups and the minimal number k of broadcasting parties that allow for the reproduction of a given set of correlations quantify their multipartite nonlocal content. We show how upper bounds on m and lower bounds on k can be computed from the violation of the Mermin-Svetlichny inequalities. While n-partite Greenberger-Horne-Zeilinger states violate these inequalities maximally, we find that W states violate them only by a very small amount. application/pdf https://sonar.ch/global/documents/21304 eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevLett.103.090503 info:eu-repo/semantics/altIdentifier/pmid/19792772 info:eu-repo/semantics/openAccess Physical review letters. - 2009 Quantifying multipartite nonlocality. http://purl.org/coar/resource_type/c_6501
