Mermin, \"Simple unified form for the major no-hidden-variables theorems,\" Phys. Rev. Lett., 65(27):3373-3376, 1990], but generalized to n binary variables and m constraints. We show that, whenever there is a perfect entangled protocol for such a game, there exists a set of binary observables with commutations and products similar to those exhibited by Mermin. We also show how to derive upper bounds strictly below 1 for the the maximum entangled success probability of some BCS games. These results are partial progress towards a larger project to determine the computational complexity of deciding whether a given instance of a BCS game admits a perfect entangled strategy or not.", "revisions": [ { "version": "v3", "updated": "2013-10-16T04:37:21.000Z" } ], "analyses": { "keywords": [ "binary constraint system games", "characterization", "bcs game admits", "maximum entangled success probability", "major no-hidden-variables theorems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1209.2729C" } } }
