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…

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…
