In addition, we study the geometric measure of pure three-qubit states systematically in virtue of a canonical form of their two-qubit reduced states, and derive analytical formulae for a three-parameter family of three-qubit states. Based on this result, we further show that the W state is the maximally entangled three-qubit state with respect to the geometric measure.", "revisions": [ { "version": "v6", "updated": "2012-04-19T13:41:09.000Z" } ], "analyses": { "subjects": [ "03.67.Mn", "02.10.Yn", "03.65.Ud", "03.65.Wj" ], "keywords": [ "geometric measure", "pure multipartite states", "entanglement", "symmetric three-qubit states", "symmetric multiqubit states" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "year": 2010, "month": "Sep", "volume": 82, "number": 3, "pages": "032301" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvA..82c2301C" } } }
