    "abstract": "We prove that all purifications of a non-factorable state (i.e., the state\nwhich cannot be expressed in a form $\\rho_{AB}=\\rho_A\\otimes\\rho_B$) are\nentangled. We also show that for any bipartite state there exists a pair of\nmeasurements which are correlated on this state if and only if the state is\nnon-factorable.",
