摘要：

We show that an optimal dense coding protocol D can be constructed with genuine multipartite entangled states, one-dimensional cluster states. We also give a teleportation scheme T by using the one-dimensional cluster states. Both D and T reveal some intrinsic entanglement properties of the one-dimensional cluster states, and indicate that we may in a sense extract the amount of entanglement of n/2 Bell states (or n-3/2 Bell states plus a tripartite GHZ state) from an n-particle one-dimensional cluster state. Our schemes can also be used to implement controlled quantum communication. (c) 2006 Elsevier B.V. All rights reserved.
