Separability and distillability of multiparticle quantum systems

Quantum Physics 2009-01-23 v2

Abstract

We present a family of 3--qubit states to which any arbitrary state can be depolarized. We fully classify those states with respect to their separability and distillability properties. This provides a sufficient condition for nonseparability and distillability for arbitrary states. We generalize our results to NN--particle states.
