Multipartite entanglement for continuous variables: A quantum teleportation network

We show that one single-mode squeezed state distributed among N parties usi ng linear optics suffices to produce a truly N-partite entangled state for any nonzero squeezing and arbitrarily many parties. From this N-partite ent angled state, via quadrature measurements of N - 2 modes, bipartite entangl ement between any two of the N parties can be "distilled," which enables qu antum teleportation with an experimentally determinable fidelity better tha n could be achieved in any classical scheme.
