摘要：

Probabilistically reversible quantum measurements are considered from the information-theoretical point of view. It is found that an upper bound on the probability of a reversing quantum measurement is given by the generalized Bhattacharyya overlap of conditional probabilities of the measurement outcomes. The relation between the upper bound of the probability and the information obtained by the quantum measurement is also discussed.
