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…
An additive and operational entanglement measure: conditional entanglement of mutual information
Dong Yang, Michal Horodecki, Z. D. Wang
Based on the monogamy of entanglement, we develop the technique of quantum conditioning to build an {\it additive} entanglement measure: the conditional entanglement of mutual info…
Extending Bell inequalities to more parties
Yu-Chun Wu, Piotr Badziag, Marcin Wieśniak +1
We describe a method of extending Bell inequalities from to parties and formulate sufficient conditions for our method to produce tight inequalities from tight inequaliti…
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…
Nonmaximally entangled states can be better for multiple linear optical teleportation
Joanna Modlawska, Andrzej Grudka
We investigate multiple linear optical teleportation in the Knill-Laflamme-Milburn scheme with both maximally and nonmaximally entangled states. We show that if the qubit is telepo…
