We show that, for any choice of 3 MUBs and at least one choice of a larger number of MUBs, the best possible entropic uncertainty relation can be only marginally better than the one that trivially follows from the relation by Maassen and Uffink (PRL, 1987) for 2 bases.", "revisions": [ { "version": "v2", "updated": "2010-07-16T13:44:17.000Z" } ], "analyses": { "keywords": [ "entropic uncertainty relation", "standard construction", "prime dimension", "larger number", "quantum state" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0909.3720A" } } }
