    "abstract": "The security of a cryptographic key that is generated by communication\nthrough a noisy quantum channel relies on the ability to distill a shorter\nsecure key sequence from a longer insecure one. For an important class of\nprotocols, which exploit tomographically complete measurements on entangled\npairs of any dimension, we show that the noise threshold for classical\nadvantage distillation is identical with the threshold for quantum entanglement\ndistillation. As a consequence, the two distillation procedures are equivalent:\nneither offers a security advantage over the other.",
