摘要： We consider the problem of trying to send a single classical bit through an amplitude-damping channel when two transmissions through the channel are available as a resource. It is demonstrated that two entangled transmissions can enhance the receiver's capability of making a correct inference under certain conditions compared with two product-state transmissions.

Key words: two transmissions, entanglement, amplitude-damping channel, average probability of error
