In particular, we provide an explicit, finite method for constructing observables in an unstructured d-dimensional system so that an arbitrary known pure state has any Schmidt decomposition with respect to an induced bipartite tensor product structure. In effect, this article demonstrates that in a finite-dimensional Hilbert space, entanglement properties can always be shifted from the state to the observables and all pure states are equivalent as entanglement resources in the ideal case of complete control of observables.", "revisions": [ { "version": "v1", "updated": "2011-02-04T16:21:28.000Z", "title": "Observables Can Be Tailored to Make Any Pure State Entangled (or Not)", "comment": "4 pages, no figures" }, { "version": "v2", "updated": "2017-01-04T10:13:06.000Z" } ], "analyses": { "subjects": [ "03.65.Ud", "03.65.Aa", "03.67.Mn" ], "keywords": [ "pure state", "observables", "finite-dimensional hilbert space", "entanglement properties", "induced bipartite tensor product structure" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
