%0 Journal Article %T Irreversibility in asymptotic manipulations of entanglement %A G. Vidal %A J. I. Cirac %J Physics %D 2001 %I arXiv %R 10.1103/PhysRevLett.86.5803 %X We show that the process of entanglement distillation is irreversible by showing that the entanglement cost of a bound entangled state is finite. Such irreversibility remains even if extra pure entanglement is loaned to assist the distillation process. %U http://arxiv.org/abs/quant-ph/0102036v2
