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