    "abstract": "We propose a probabilistic quantum cloning scheme using\nGreenberger-Horne-Zeilinger states, Bell basis measurements, single-qubit\nunitary operations and generalized measurements, all of which are within the\nreach of current technology. Compared to another possible scheme via Tele-CNOT\ngate [D. Gottesman and I. L. Chuang, Nature 402, 390 (1999)], the present\nscheme may be used in experiment to clone the states of one particle to those\nof two different particles with higher probability and less GHZ resources.",
