Abstract

Recently the explicit applicability of bound entanglement in quantum cryptography has been shown. In this paper some of recent results respecting this topic are reviewed. In particular relevant notions and definitions are reminded. A new construction of bound entangled states containing secure correlations is presented. It provides low-dimensional bound entangled states with nonzero distillable key.
