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