摘　　要：We present a complete multiple round quantum dense coding scheme for improving the source ca-pacity of that introduced recently by Zhang et al. The receiver resorts to two qubits for storing the four local unitary operations in each round.We present a complete multiple round quantum dense coding scheme for improving the source capacity of that introduced recently by Zhang et al.
