    "abstract": "We present two method for optimal entanglement concentration from pure\nentangled states by local actions only. However a prior knowledge of the\nSchmidt coefficients is required. The first method is optimally efficient only\nwhen a finite ensemble of pure entangled states are available whereas the\nsecond method realizes the single pair optimal concentration probability. We\nalso propose an entanglement assisted method which is again optimally efficient\neven for a single pair. We also discuss concentrating entanglement from\nN-partite cat like states.",
