Abstract Superadditivity is a special property in quantum communication theory. We present the optimal measurement for a mixed-state ensemble and calculate the amount of one-shot capacity, which is connected to the intensity of noise of the channel. Then the property of superadditivity is preserved when the mixed-state ensemble is used to transmit information.
