Scattering theory of plasmon-assisted entanglement transfer and distillation
J. L. van Velsen, J. Tworzydlo, C. W. J. Beenakker
We analyse the quantum mechanical limits to the plasmon-assisted entanglement transfer observed by E. Altewischer, M.P. van Exter, and J.P. Woerdman [Nature, 418, 304 (2002)]. The…
Anomalous power law of quantum reversibility for classically regular dynamics
Ph. Jacquod, I. Adagideli, C. W. J. Beenakker
The Loschmidt Echo M(t) (defined as the squared overlap of wave packets evolving with two slightly different Hamiltonians) is a measure of quantum reversibility. We investigate its…
Quantum-optical communication rates through an amplifying random medium
J. Tworzydlo, C. W. J. Beenakker
We study the competing effects of stimulated and spontaneous emission on the information capacity of an amplifying disordered waveguide. At the laser threshold the capacity reaches…
