Abstract

We show that one single-mode squeezed state distributed among N parties using linear optics suffices to produce a truly N-partite entangled state for any nonzero squeezing and arbitrarily many parties. From this N-partite entangled state, via quadrature measurements of N2 modes, bipartite entanglement between any two of the N parties can be “distilled,” which enables quantum teleportation with an experimentally determinable fidelity better than could be achieved in any classical scheme.
