Teleportation and Dense Coding with Genuine Multipartite Entanglement
Ye Yeo, Wee Kang Chua
abstract: We present an explicit protocol ${\cal E}_0$ for faithfully teleporting an
arbitrary two-qubit state via a genunie four-qubit entangled state. By
construction, our four-partite state is not reducible to a pair of Bell states.
Its properties are compared and contrasted with those of the four-party GHZ and
W states. We also give a dense coding scheme ${\cal D}_0$ involving our state
as a shared resource of entanglement. Both ${\cal D}_0$ and ${\cal E}_0$
indicate that our four-qubit state is a likely candidate for the genunine
four-partite analogue to a Bell state.
