Dür, W.Cirac, Juan IgnacioTarrach, R., 1948-2010-06-092010-06-0919990031-9007https://hdl.handle.net/2445/12804We 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 N-particle states.4 p.application/pdfeng(c) American Physical Society, 1999Teoria quànticaTeoria de camps (Física)Quantum mechanics, field theories, and special relativityQuantum theoryField theory (Physics)info:eu-repo/semantics/article189679info:eu-repo/semantics/openAccess
