    "abstract": "We show that no entanglement is necessary to distribute entanglement; that\nis, two distant particles can be entangled by sending a third particle that is\nnever entangled with the other two. Similarly, two particles can become\nentangled by continuous interaction with a highly mixed mediating particle that\nnever itself becomes entangled. We also consider analogous properties of\ncompletely positive maps, in which the composition of two separable maps can\ncreate entanglement.",
