Bang-Bang control of a qubit coupled to a quantum critical spin bath
Davide Rossini, Paolo Facchi, Rosario Fazio +5
We analytically and numerically study the effects of pulsed control on the decoherence of a qubit coupled to a quantum spin bath. When the environment is critical, decoherence is f…
Mott-insulating and glassy phases of polaritons in 1D arrays of coupled cavities
Davide Rossini, Rosario Fazio
By means of analytical and numerical methods we analyze the phase diagram of polaritons in one-dimensional coupled cavities. We locate the phase boundary, discuss the behavior of t…
Entanglement in Many-Body Systems
Luigi Amico, Rosario Fazio, Andreas Osterloh +1
The recent interest in aspects common to quantum information and condensed matter has prompted a prosperous activity at the border of these disciplines that were far distant until…
From perfect to fractal transmission in spin chains
Gabriele De Chiara, Davide Rossini, Simone Montangero +1
Perfect state transfer is possible in modulated spin chains, imperfections however are likely to corrupt the state transfer. We study the robustness of this quantum communication p…
Dynamics of entanglement in quantum computers with imperfections
Simone Montangero, Giuliano Benenti, Rosario Fazio
The dynamics of the pairwise entanglement in a qubit lattice in the presence of static imperfections exhibits different regimes. We show that there is a transition from a perturbat…
