摘要
We apply the inseparability criterion for systems, local filtering and Bennett et al. purification protocol [Phys. Rev. Lett. {\bf 76}, 722 (1996)] to show how to distill {\it any} inseparable system. The extended protocol is illustrated geometrically by means of the state parameters in the Hilbert-Schmidt space.
