Among them, pseudotelepathy enables two or more players to win systematically at some cooperative games with no need for communication between them, a restriction that would make the task impossible in a classical world. We investigate the power of multipartite entanglement for pseudotelepathy. Some known games that can be won with tripartite entanglement cannot be won with bipartite entanglement, but they can be won with bipartite nonsignaling resources such as the so-called Popescu\u2013Rohrlich nonlocal box. We exhibit a five-player game that can be won with tripartite entanglement, but not with arbitrary bipartite nonsignaling resources even in the presence of arbitrary five-partite classical resources. This illustrates both the power of bipartite nonsignaling resources (over bipartite entanglement) and the even superior power of tripartite entanglement.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2607361123","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T16:59:47Z","timestamp":1790269187000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":0,"title":["On the power of multipartite entanglement for pseudotelepathy"],"prefix":"10.1073","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4380-117X","authenticated-orcid":false,"given":"Gilles","family":"Brassard","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0161xgx34","id-type":"ROR","asserted-by":"publisher"}],"name":"D\u00e9partement d\u2019informatique et de recherche op\u00e9rationnelle, Universit\u00e9 de Montr\u00e9al","place":["Montr\u00e9al, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7355-4632","authenticated-orcid":false,"given":"Xavier","family":"Coiteux-Roy","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03yjb2x39","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Computer Science, University of Calgary","place":["Calgary, Canada"]},{"id":[{"id":"https:\/\/ror.org\/03yjb2x39","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Physics and Astronomy, University of Calgary","place":["Calgary, Canada"]},{"id":[{"id":"https:\/\/ror.org\/03yjb2x39","id-type":"ROR","asserted-by":"publisher"}],"name":"Institute for Quantum Science and Technology, University of Calgary","place":["Calgary, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8692-0151","authenticated-orcid":false,"given":"R\u00e9mi","family":"Ligez","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0161xgx34","id-type":"ROR","asserted-by":"publisher"}],"name":"D\u00e9partement d\u2019informatique et de recherche op\u00e9rationnelle, Universit\u00e9 de Montr\u00e9al","place":["Montr\u00e9al, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRev.47.777"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0305004100013554"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02650179"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.1985.0070"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.70.1895"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.67.661"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.68.557"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.56.1201"},{"key":"e_1_3_4_9_2","doi-asserted-by":"crossref","unstructured":"H.
