    "abstract": "We discuss the criteria presently used for evaluating the efficiency of\nquantum teleportation schemes for continuous variables. Using an argument based\nupon the difference between 1-to-2 quantum cloning (quantum duplication) and\n1-to-infinity cloning (classical measurement), we show that a fidelity value\nlarger than 2/3 is required for successful quantum teleportation of coherent\nstates. This value has not been reached experimentally so far.",
