We introduce a generalization of one-way superdense coding to two-way communication protocols for transmitting classical bits by using entangled quantum pairs. The proposed protocol caters for provision of entangled pairs, which is assumed to be given in one-way superdense coding. The proposed protocol gives a 50 to the classical protocol. Even when decoherence is taken into consideration, the quantum protocol performs better as long as the decoherence time is not extremely short.
