Local versus non-local information in quantum information theory: formalism and phenomena
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki +4
In spite of many results in quantum information theory, the complex nature of compound systems is far from being clear. In general the information is a mixture of local, and non-lo…
A dressing of zero-range potentials and electron-molecule scattering problem at Ramsauer-Townsend minimum
S. Leble, S. Yalunin
A dressing technique is used to improve zero range potential (ZRP) model. We consider a Darboux transformation starting with a ZRP, the result of the "dressing" gives a potential w…
Bound entanglement maximally violating Bell inequalities: quantum entanglement is not equivalent to quantum security
Remigiusz Augusiak, Pawel Horodecki
It is shown that Smolin four-qubit bound entangled states [Phys. Rev. A, 63 032306 (2001)] can maximally violate two-setting Bell inequality similar to standard CHSH inequality. Su…
Locking entanglement measures with a single qubit
Karol Horodecki, Michal Horodecki, Pawel Horodecki +1
We study the loss of entanglement of bipartite state subjected to discarding or measurement of one qubit. Examining the behavior of different entanglement measures, we find that en…
Non-additivity of quantum capacity for multiparty communication channels
W. Dür, J. I. Cirac, P. Horodecki
We investigate multiparty communication scenarios where information is sent from several sender to several receivers. We establish a relation between the quantum capacity of multip…
