    "abstract": "In this paper, we present sufficient conditions for states to have positive\ndistillable key rate. Exploiting the conditions, we show that the bound\nentangled states given by Horodecki et al. [Phys. Rev. Lett. 94, 160502 (2005),\nquant-ph/0506203] have nonzero distillable key rate, and finally exhibit a new\nclass of bound entangled states with positive distillable key rate, but with\nnegative Devetak-Winter lower bound of distillable key rate for the ccq states\nof their privacy squeezed versions.",
