Complete extension: the non-signaling analog of quantum purification
Marek Winczewski, Tamoghna Das, John H. Selby +5
Deriving quantum mechanics from information-theoretic postulates is a recent research direction taken, in part, with the view of finding a beyond-quantum theory; once the postulate…
Entanglement distillation by extendible maps
Lukasz Pankowski, Fernando G. S. L. Brandao, Michal Horodecki +1
It is known that from entangled states that have positive partial transpose it is not possible to distill maximally entangled states by local operations and classical communication…
On some entropic entanglement parameter
Barbara Synak-Radtke, Lukasz Pankowski, Michal Horodecki +1
In this paper we present the quantity, which is an entanglement parameter. Its origin is very intriguing, because its construction is motivated by separability criteria based on un…
Low dimensional bound entanglement with one-way distillable cryptographic key
Karol Horodecki, Lukasz Pankowski, Michal Horodecki +1
We provide a class of bound entangled states that have positive distillable secure key rate. The smallest state of this kind is , which shows that peculiar security co…
