Characterization of distillability of entanglement in terms of positive
maps
Lieven Clarisse
abstract: A necessary and sufficient condition for 1-distillability is formulated in
terms of decomposable positive maps. As an application we provide insight into
why all states violating the reduction criterion map are distillable and
demonstrate how to construct such maps in a systematic way. We establish a
connection between a number of existing results, which leads to an elementary
proof for the characterisation of distillability in terms of 2-positive maps.
