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…
No-local-broadcasting theorem for quantum correlations
Marco Piani, Pawel Horodecki, Ryszard Horodecki
We prove that the correlations present in a multipartite quantum state have an \emph{operational} quantum character as soon as the state does not simply encode a multipartite class…
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…
Entanglement-swapping boxes and their communication properties
Andrzej Grudka, Michal Horodecki, Pawel Horodecki +2
We pose the fundamental question of communication properties of primitives irrespectively of their implementation. To illustrate the idea we introduce the concept of entanglement-s…
Unconditional privacy over channels which cannot convey quantum information
Karol Horodecki, Michal Horodecki, Pawel Horodecki +2
By sending systems in specially prepared quantum states, two parties can communicate without an eavesdropper being able to listen. The technique, called quantum cryptography, enabl…
