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…

Classical versus quantum errors in quantum computation of dynamical systems
Davide Rossini, Giuliano Benenti, Giulio Casati
We analyze the stability of a quantum algorithm simulating the quantum dynamics of a system with different regimes, ranging from global chaos to integrability. We compare, in these…
