Superdense coding is a distinct property of quantum entanglement. In this paper, we show that the bipartite three-particle W state can transmit 3 bits by sending two qubits using single qubit operations. This has justified previous conjecture (Agrawal and Pati, Phys. Rev. A 74(6), 062320 2006). Similar result holds for hyperentangled W states.
