Abstract = {We introduce a measure of the compatibility between quantum states---the
likelihood that two density matrices describe the same object. Our measure
is motivated by two elementary requirements, which lead to a natural
definition. We list some properties of this measure, and discuss its relation to the
problem of combining two observers' states of knowledge.},
