On bound entanglement assisted distillation
We investigate asymptotic distillation of entanglement in the presence of an
unlimited amount of bound entanglement for bi-partite systems. We show that the
distillability is still bounded by the relative entropy of entanglement. This
offers a strong support to the fact that bound entanglement does not improve
distillation of entanglement.Comment: 9 pages, no figures, minor typos correcte
Landauer's erasure, error correction and entanglement
Classical and quantum error correction are presented in the form of Maxwell's
demon and their efficiency analyzed from the thermodynamic point of view. We
explain how Landauer's principle of information erasure applies to both cases.
By then extending this principle to entanglement manipulations we rederive
upper bounds on purification procedures thereby linking the ''no local increase
of entanglement'' principle to the Second Law of thermodynamics.Comment: 11 pages, 1 figure, to appear in The Proceedings of The Royal Societ
