On quantum cryptography with bipartite bound entangled states
Pawel Horodecki, Remigiusz Augusiak
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 partic…
A general scheme for construction of scalar separability criteria from positive maps
Remigiusz Augusiak, Julia Stasińska
We present a general scheme that allows for construction of scalar separability criteria from positive but not completely positive maps. The concept is based on a decomposition of…
Beyond the standard entropic inequalities: stronger scalar separability criteria and their applications
Remigiusz Augusiak, Julia Stasińska, Pawel Horodecki
Recently it was shown that if a given state fulfils the reduction criterion it must also satisfy the known entropic inequalities. Now the questions arises whether on the assumption…
Generalised Smolin states and their properties
Remigiusz Augusiak, Pawel Horodecki
Four qubit bound entangled Smolin states are generalised in a natural way to even number of qubits. They are shown to maximally violate simple correlation Bell inequalities and, as…
