This mothod of two-way communication scheme addresses the main drawback of superdense coding, namely the entanglement distribution. By integrating the entanglement distribution into the communication protocol itself, it is used to convey information bits as well as distributing the EPR pairs between partecipants. The main difference introduced in the quantum scheme, we are able to transmit three information bits in a single slot, one bit due to the protocol and two bits due to superdense coding over an EPR pair.
