On quantum cryptography with bipartite bound entangled states
Paweł Horodecki, Remigiusz Augusiak · arXiv (Cornell University) · 2007
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. The new construction of bound entangled states containing secure correlations is presented. It provides low dimensional 6\otimes6 bound entangled states with nonzero distillable key.
