Broadcasting of entanglement via local copying
V. Buzek, V. Vedral, M. B. Plenio, P. L. Knight, M. Hillery
abstract: We show that inseparability of quantum states can be partially broadcasted
(copied, cloned) with the help of local operations, i.e. distant parties
sharing an entangled pair of spin 1/2 states can generate two pairs of
partially nonlocally entangled states using only local operations. This
procedure can be viewed as an inversion of quantum purification procedures.
