Efficient Superdense Coding with W States

Efficient Superdense Coding with W States 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Theoretical Physics Springer Journals

Abstract

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.
