The method is based on the generation of 2-qubit Bell states and the introduction of quantum noise in a controlled way on one of the state subsystems. The efficiency of the optimal estimation, achieved by a Bell measurement, is shown to outperform quantum process tomography.", "revisions": [ { "version": "v2", "updated": "2011-12-21T15:53:43.000Z" } ], "analyses": { "subjects": [ "42.50.Dv", "03.67.Bg", "03.67.Hk", "42.50.Ex" ], "keywords": [ "optimal noise estimation", "general pauli channel", "experimental realization", "outperform quantum process tomography", "optimal estimation protocol" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2011, "month": "Dec", "volume": 107, "number": 25, "pages": 253602 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011PhRvL.107y3602C" } } }
