The Kossakowski Matrix and Strict Positivity of Markovian Quantum Dynamics
Julián Agredo, Franco Fagnola, Damiano Poletti
We investigate the relationship between strict positivity of the Kossakowski matrix, irreducibility and positivity improvement properties of Markovian Quantum Dynamics. We show tha…

Environment induced entanglement in Gaussian open quantum systems
A. Dhahri, F. Fagnola, D. Poletti +1
We show that a bipartite Gaussian quantum system interacting with an external Gaussian environment may possess a unique Gaussian entangled stationary state and that any initial sta…

The decoherence-free subalgebra of Gaussian Quantum Markov Semigroups
Julián Agredo, Franco Fagnola, Damiano Poletti
We demonstrate a method for finding the decoherence-subalgebra of a Gaussian quantum Markov semigroup on the von Neumann algebra $\mathcal{B}(Γ(\mathbb{C…
