Description

A quantum system is called inseparable if its density matrix cannot be written as a mixture of product states. In this Letter we apply the separability criterion, local filtering, and Bennett et al.distillation protocol [Phys.Rev.Lett.76, 722 (1996)] to show that any inseparable 2x2 system represents the entanglement which, however small, can be distilled to a singlet form. copyright 1997 The American Physical Society
