    "abstract": "We consider entanglement-assisted remote quantum state manipulation of\nbi-partite mixed states. Several aspects are addressed: we present a class of\nmixed states of rank two that can be transformed into another class of mixed\nstates under entanglement-assisted local operations with classical\ncommunication, but for which such a transformation is impossible without\nassistance. Furthermore, we demonstrate enhancement of the efficiency of\npurification protocols with the help of entanglement-assisted operations.\nFinally, transformations from one mixed state to mixed target states which are\nsufficiently close to the source state are contrasted to similar\ntransformations in the pure-state case.",
