    "abstract": "We describe a protocol which can be used to generate any N-partite pure\nquantum state using Einstein-Podolsky-Rosen (EPR) pairs. This protocol employs\nonly local operations and classical communication between the N parties\n(N-LOCC). In particular, we rely on quantum data compression and teleportation\nto create the desired state. This protocol can be used to obtain upper bounds\nfor the bipartite entanglement of formation of an arbitrary N-partite pure\nstate, in the asymptotic limit of many copies. We apply it to a few\nmultipartite states of interest, showing that in some cases it is not optimal.\nGeneralizations of the protocol are developed which are optimal for some of the\nexamples we consider, but which may still be inefficient for arbitrary states.",
