    "abstract": "The concept of entanglement splitting is introduced by asking whether it is\npossible for a party possessing half of a pure bipartite quantum state to\ntransfer some of his entanglement with the other party to a third party. We\ndescribe the unitary local transformation for symmetric and isotropic splitting\nof a singlet into two branches that leads to the highest entanglement of the\noutput. The capacity of the resulting quantum channels is discussed. Using the\nsame transformation for less than maximally entangled pure states, the\nentanglement of the resulting states is found. We discuss whether they can be\nused to do teleportation and to test the Bell inequality. Finally we generalize\nto entanglement splitting into more than two branches.",
