    "abstract": "Methods for distilling maximally entangled tripartite (GHZ) states from\narbitrary entangled tripartite pure states are described. These techniques work\nfor virtually any input state. Each technique has two stages which we call\nprimary and secondary distillation. Primary distillation produces a GHZ state\nwith some probability, so that when applied to an ensemble of systems, a\ncertain percentage is discarded. Secondary distillation produces further GHZs\nfrom the discarded systems. These protocols are developed with the help of an\napproach to quantum information theory based on absolutely selective\ninformation, which has other potential applications.",
