Decoherence induced by interacting quantum spin baths
Davide Rossini, Tommaso Calarco, Vittorio Giovannetti +2
We study decoherence induced on a two-level system coupled to a one-dimensional quantum spin chain. We consider the cases where the dynamics of the chain is determined by the Ising…
Information transfer rates in spin quantum channels
Davide Rossini, Vittorio Giovannetti, Rosario Fazio
We analyze the communication efficiency of quantum information transfer along unmodulated spin chains by computing the communication rates of various protocols. The effects of temp…
Conservative chaotic map as a model of quantum many-body environment
Davide Rossini, Giuliano Benenti, Giulio Casati
We study the dynamics of the entanglement between two qubits coupled to a common chaotic environment, described by the quantum kicked rotator model. We show that the kicked rotator…
Decoherence by engineered quantum baths
Davide Rossini, Tommaso Calarco, Vittorio Giovannetti +2
We introduce, and determine decoherence for, a wide class of non-trivial quantum spin baths which embrace Ising, XY and Heisenberg universality classes coupled to a two-level syste…
