    "abstract": "Recently M. Horodecki, P. Horodecki and R. Horodecki have introduced a set of\ndensity matrices of two spin-1 particles from which it is not possible to\ndistill any maximally entangled states, even though the density matrices are\nentangled. Thus these density matrices do not allow reliable teleportation.\nHowever it might nevertheless be the case that these states can be used for\nteleportation, not reliably, but still with fidelity greater than that which\nmay be achieved with a classical scheme. We show that, at least for some of\nthese density matrices, teleportation cannot be achieved with better than\nclassical fidelity.",
