It is similar in form and in some cases has a close connection to the weak value of an observable, but instead of describing an effective interaction when the coupling is weak, it describes a coupling of any strength but only to qubit meters. The generalization of the concept for a coupling of a composite system to a multi-qubit meter provides an explanation of some current experiments.", "revisions": [ { "version": "v1", "updated": "2010-07-29T18:18:47.000Z" } ], "analyses": { "subjects": [ "03.65.Ta", "03.65.Ud", "03.67.Bg", "42.50.Xa" ], "keywords": [ "weak value", "modular value", "quantum observables", "post-selected quantum system", "current experiments" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2010, "month": "Dec", "volume": 105, "number": 23, "pages": 230401 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvL.105w0401K" } } }
