    "abstract": "We introduce a measure of the compatibility between quantum states--the\nlikelihood that two density matrices describe the same object. Our measure is\nmotivated by two elementary requirements, which lead to a natural definition.\nWe list some properties of this measure, and discuss its relation to the\nproblem of combining two observers\u0027 states of knowledge.",
