    "abstract": "We show how shared entanglement, together with classical communication and\nlocal quantum operations, can be used to perform an arbitrary collective\nquantum operation upon N spatially-separated qubits. A simple\nteleportation-based protocol for achieving this, which requires 2(N-1) ebits of\nshared, bipartite entanglement and 4(N-1) classical bits, is proposed. In terms\nof the total required entanglement, this protocol is shown to be optimal for\neven N in both the asymptotic limit and for `one-shot\u0027 applications.",
