    "abstract": "We introduce entanglement measures to describe entanglement in a\nthree-particle system and apply it to studying broadcasting of entanglement in\nthree-particle GHZ state. We show that entanglement of three-qubit GHZ state\ncan be partially broadcasted with the help of local or non-local copying\nprocesses. It is found that non-local cloning is much more efficient than local\ncloning for the broadcasting of entanglement.",
