Gaussian quantum Markov semigroups on finitely many modes admitting a normal invariant state
Federico Girotti, Damiano Poletti
Gaussian quantum Markov semigroups (GQMSs) are of fundamental importance in modelling the evolution of several quantum systems. Moreover, they represent the noncommutative generali…

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 Spectral Gap of a Gaussian Quantum Markovian Generator
Franco Fagnola, Damiano Poletti, Emanuela Sasso +1
Gaussian quantum Markov semigroups are the natural non-commutative extension of classical Ornstein-Uhlenbeck semigroups. They arise in open quantum systems of bosons where canonica…
