Phys. Rev. A 66, 014303 (2002) [2 pages]Distillable entanglement of multiple copies of Bell statesReceived 3 April 2002; published 18 July 2002 It is impossible to discriminate four Bell states through local operations and classical communication, if only one copy is provided. To complete this task, two copies will suffice and be necessary. When n copies are provided, we show that the distillable entanglement is exactly n-2. © 2002 The American Physical Society URL:
