    "abstract": "We show that inseparability of quantum states can be partially broadcasted\n(copied, cloned) with the help of local operations, i.e. distant parties\nsharing an entangled pair of spin 1/2 states can generate two pairs of\npartially nonlocally entangled states using only local operations. This\nprocedure can be viewed as an inversion of quantum purification procedures.",
