    "abstract": "Disentanglement is the process which transforms a state $\\rho$ of two\nsubsystems into an unentangled state, while not effecting the reduced density\nmatrices of each of the two subsystems. Recently Terno showed that an arbitrary\nstate cannot be disentangled into a tensor product of its reduced density\nmatrices. In this letter we present various novel results regarding\ndisentanglement of states. Our main result is that there are sets of states\nwhich cannot be successfuly disentangled (not even into a separable state).\nThus, we prove that a universal disentangling machine cannot exist.",
