    "abstract": "Deterministic extraction of Bell pairs from a finite number of partially\nentangled pairs is discussed. We derive the maximum number of Bell pairs that\ncan be obtained with probability 1 by local operations and classical\ncommunication. It is proved that the optimal deterministic concentration needs\nonly a two-pair collective manipulation in each step, and that a collective\nmanipulation of all entangled pairs is not necessary. Finally, this scheme\nreveals an entanglement measure for the deterministic concentration.",
