Decoherence of number states in phase-sensitive reservoirs
A. Serafini, S. De Siena, F. Illuminati
The non-unitary evolution of initial number states in general Gaussian environments is solved analytically. Decoherence in the channels is quantified by determining explicitly the…
Determination of continuous variable entanglement by purity measurements
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We classify the entanglement of two--mode Gaussian states according to their degree of total and partial mixedness. We derive exact bounds that determine maximally and minimally en…
Entanglement and purity of two-mode Gaussian states in noisy channels
Alessio Serafini, Fabrizio Illuminati, Matteo G. A. Paris +1
We study the evolution of purity, entanglement and total correlations of general two--mode Gaussian states of continuous variable systems in arbitrary uncorrelated Gaussian environ…
Symplectic invariants, entropic measures and correlations of Gaussian states
Alessio Serafini, Fabrizio Illuminati, Silvio De Siena
We present a derivation of the Von Neumann entropy and mutual information of arbitrary two--mode Gaussian states, based on the explicit determination of the symplectic eigenvalues…
Purity of Gaussian states: measurement schemes and time-evolution in noisy channels
M. G. A. Paris, F. Illuminati, A. Serafini +1
We present a systematic study of the purity for Gaussian states of single-mode continuous variable systems. We prove the connection of purity to observable quantities for these sta…
