Entanglement purification protocol for a mixture of a pure entangled state and a pure product state
Mikolaj Czechlewski, Andrzej Grudka, Satoshi Ishizaka +1
We present an entanglement purification protocol for a mixture of a pure entangled state and a pure product state, which are orthogonal to each other. The protocol is combination o…
W-like bound entangled states and secure key distillation
Remigiusz Augusiak, Pawel Horodecki
We construct multipartite entangled states with underlying W-type structure satisfying positive partial transpose (PPT) condition under any (N-1)|1 partition. Then we show how to d…
Adaptive quantum teleportation
Joanna Modlawska, Andrzej Grudka
We consider multiple teleportation in the Knill-Laflamme-Milburn (KLM) scheme. We introduce adaptive teleportation, i.e., such that the choice of entangled state used in the next t…
Structural approximations to positive maps and entanglement breaking channels
J. K. Korbicz, M. L. Almeida, J. Bae +2
Structural approximations to positive, but not completely positive maps are approximate physical realizations of these non-physical maps. They find applications in the design of di…
Entanglement-redistribution boxes
Andrzej Grudka, Michal Horodecki, Pawel Horodecki +2
We establish a framework to study the classical-communication properties of primitive local operations assisted by classical communication which realize various redistributions of…
Increasing singlet fraction with entanglement swapping
Joanna Modlawska, Andrzej Grudka
We consider entanglement swapping for certain mixed states. We assume that the initial states have the same singlet fraction and show that the final state can have singlet fraction…
