Sudden death of effective entanglement

K. Roszak, P. Horodecki, R. Horodecki

Sudden death of entanglement is a well-known effect resulting from the finite volume of separable states. We study the case when the observer has a limited measurement capability a…

Unified Framework for Correlations in Terms of Local Quantum Observables

A. Acín, R. Augusiak, D. Cavalcanti +5

We provide a unified framework for nonsignalling quantum and classical multipartite correlations, allowing all to be written as the trace of some local (quantum) measurements multi…

Nonadditivity of quantum and classical capacities for entanglement breaking multiple-access channels and butterfly network

Andrzej Grudka, Pawel Horodecki

We analyze quantum network primitives which are entanglement-breaking. We show superadditivity of quantum and classical capacity regions for quantum multiple-access channel and qua…

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…

Quantum superadditivity in linear optics networks: sending bits via multiple access Gaussian channels

L. Czekaj, J. K. Korbicz, R. W. Chhajlany +1

We study classical capacity regions of quantum Gaussian multiple access channels (MAC). In classical variants of such channels, whilst some capacity superadditivity-type effects su…

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…
