Abstract: | The problem of sending a single classical bit through a generalized
amplitude damping channel is considered. When two transmissions
through the channel are available as a resource, we find that two
entangled transmissions can enhance the capability of receiver's
judging information correctly under certain conditions compared with
two product-state transmissions. In addition, we find a special case
in which the two entangled transmissions can always make a
classical bit more effectively disable the noise influence. |
