Our argument is based on a treatment of the Schroedinger dynamics of the composite of a quantum microsystem, S, and a macroscopic measuring apparatus, I, consisting of N interacting particles. The pointer positions of this apparatus are represented by orthogonal subspaces of its representative Hilbert space that are simultaneous eigenspaces of coarse-grained macroscopic observables. By taking explicit account of their macroscopicality via a large deviation principle, we prove that, for a suitably designed apparatus I, the evolution of the composite (S+I) leads both to the reduction of the wave packet of S and to a one-to-one correspondence between the resultant state of this microsystem and the pointer position of I, up to utterly negligible corrections that decrease exponentially with N.", "revisions": [ { "version": "v1", "updated": "2007-10-17T15:00:59.000Z" } ], "analyses": { "subjects": [ "03.65.Ta", "03.65.Ge", "02.50.Cw" ], "keywords": [ "quantum measurement problem", "schroedinger dynamics", "quantum probability", "pointer position", "large deviation principle" ], "tags": [ "conference paper", "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007AIPC..962..215S" } } }
