The introduction of \"amplitudes\" for density operators allows for a more intuitive treatment of these quantities, also pointing to a natural parallel transport. The latter is governed by a remarkable gauge theory with strong relations to the Riemann-Bures metric.", "revisions": [ { "version": "v1", "updated": "2011-06-06T07:59:49.000Z" }, { "version": "v2", "updated": "2016-04-07T09:09:52.000Z" } ], "analyses": { "keywords": [ "transition probability", "quantum system", "density operators", "natural parallel transport", "gauge theory" ], "tags": [ "conference paper", "journal article" ], "publication": { "journal": "Foundations of Physics", "year": 2011, "month": "Mar", "volume": 41, "number": 3, "pages": 288, "publisher": "Springer" }, "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011FoPh...41..288U" } } }
