Our approach is to derive a mathematical structure theorem for all the relevant covariant instruments. As a consequence of this result, we show that every Weyl-Heisenberg covariant observable can be implemented as a sequential measurement of two conjugate observables. This method is applicable both in finite and infinite dimensional Hilbert spaces, therefore covering sequential spin component measurements as well as position-momentum sequential measurements.", "revisions": [ { "version": "v1", "updated": "2011-05-25T09:32:22.000Z" } ], "analyses": { "keywords": [ "conjugate observables", "covering sequential spin component measurements", "infinite dimensional hilbert spaces", "position-momentum sequential measurements", "relevant covariant instruments" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2011, "month": "Jul", "volume": 44, "number": 28, "pages": 285304 }, "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011JPhA...44B5304C" } } }
