    "abstract": "We calculate the entanglement of formation and the entanglement of\ndistillation for arbitrary mixtures of the zero spin states on an\narbitrary-dimensional bipartite Hilbert space. Such states are relevant to\nquantum black holes and to decoherence-free subspaces based communication. The\ntwo measures of entanglement are equal and scale logarithmically with the\nsystem size. We discuss its relation to the black hole entropy law. Moreover,\nthese states are locally distinguishable but not locally orthogonal, thus\nviolating a conjecture that the entanglement measures coincide only on locally\northogonal states. We propose a slightly weaker form of this conjecture.\nFinally, we generalize our entanglement analysis to any unitary group.",
