Abstract
Probabilistically reversible quantum measurements are considered from the i nformation-theoretical point of view. It is found that an upper bound on th e probability of a reversing quantum measurement is given by the generalize d Bhattacharyya overlap of conditional probabilities of the measurement out comes. The relation between the upper bound of the probability and the info rmation obtained by the quantum measurement is also discussed.
