    "abstract": "The original purpose of measurements is to provide us with information about\na previously unknown physical property of the system observed. In the Hilbert\nspace formalism of quantum mechanics, this physical meaning of measurement\ninformation is not immediately apparent. In order to study the relationship\nbetween the Hilbert space coherence of the quantum state and the measurement\ninformation obtained in the laboratory, we introduce a generalized measurement\npostulate for finite resolution measurements. With this measurement model,\ncorrelations between non-commuting observables can be investigated. These\nexperimentally accessible correlations reveal nonclassical features in their\ndependence on the operator ordering, reflecting the particular measurement\ncontext by which they are determined.",
