The dynamics of an entangled state interacting with a single cavity mode is investigated in the presence of a random parameter. We show that the degree of entanglement decays with time and that the rate of decay is defined by features of a random parameter. Quantum teleportation through a...

We investigate the role of the cross decay rates (environment-assisted effective coupling) in a system composed by two electromagnetic modes interacting with the same reservoir. Two feasible experiments sensitive to the magnitudes and phases of these rates are described. We show that if the...

We give a detailed account of the derivation of a master equation for two-coupled cavities in the presence of dissipation. The analytical solution is presented and physical limits of interest are discussed. Firstly, we show that the decay rate of initial coherent states can be significantly...
