    "abstract": "We show that on exceeding a certain degree of mixedness (as quantified by the\nvon Neumann entropy), entangled states become useless for teleporatation. By\nincreasing the dimension of the entangled systems, this entropy threshold can\nbe made arbitrarily close to maximal. This entropy is found to exceed the\nentropy threshold sufficient to ensure the failure of dense coding.",
