Theory versus experiment for vacuum Rabi oscillations in lossy cavities (II): Direct test of uniqueness of vacuum
Marcin Wilczewski, Marek Czachor
The paper continues the analysis of vacuum Rabi oscillations we started in Part I [Phys. Rev. A {\bf 79}, 033836 (2009)]. Here we concentrate on experimental consequences for cavit…
Broadcast copies reveal the quantumness of correlations
M. Piani, M. Christandl, C. E. Mora +1
We study the quantumness of bipartite correlations by proposing a quantity that combines a measure of total correlations -- mutual information -- with the notion of broadcast copie…
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…
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…
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…
