Add to ORKGWe study the entanglement properties of the output state of a universal cloning machine. We analyse in particular bipartite and tripartite entanglement of the clones, and discuss the ``classical limit'' of infinitely many output copies.Comment: 7 pages, 1 figure, contribution to "David Mermin Festschrift", Foundations of Physic
