    "abstract": "The problem as to when two noncommuting observables are considered to have\nthe same value arises commonly, but shows a nontrivial difficulty. Here, an\nanswer is given by establishing the notion of perfect correlations between\nnoncommuting observables, and applied to obtain a criterion for precise\nmeasurements of a given observable in a given state.",
