Although this concept is at the heart of quantum mechanics, the number of these bases is unknown except for systems of dimension being a power of a prime. We develop the relation between this physical problem and the mathematical problem of finding the number of mutually orthogonal Latin squares. We derive in a simple way all known results about the unbiased bases, find their lower number, and disprove the existence of certain forms of the bases in dimensions different than power of a prime. Using the Latin squares, we construct hidden-variable models which efficiently simulate results of complementary quantum measurements.", "revisions": [ { "version": "v2", "updated": "2009-01-19T07:44:00.000Z" } ], "analyses": { "subjects": [ "03.65.Ta", "02.10.Ox" ], "keywords": [ "mutually unbiased bases", "hidden-variable models", "complementary quantum measurements", "mutually orthogonal latin squares", "unbiased bases encapsulate" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "year": 2009, "month": "Jan", "volume": 79, "number": 1, "pages": "012109" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvA..79a2109P" } } }
