Spin chain model for correlated quantum channels
Davide Rossini, Vittorio Giovannetti, Simone Montangero
We analyze the quality of the quantum information transmission along a correlated quantum channel by studying the average fidelity between input and output states and the average o…
Qubit channels with small correlations
Filippo Caruso, Vittorio Giovannetti, Chiara Macchiavello +1
We introduce a class of quantum channels with correlations acting on pairs of qubits, where the correlation takes the form of a shift operator onto a maximally entangled state. We…
Optimal control of atom transport for quantum gates in optical lattices
G. De Chiara, T. Calarco, M. Anderlini +5
By means of optimal control techniques we model and optimize the manipulation of the external quantum state (center-of-mass motion) of atoms trapped in adjustable optical potential…
A new approach to characterize qubit channels
Filippo Caruso, Vittorio Giovannetti
We analyze qubit channels by exploiting the possibility of representing two-level quantum systems in terms of characteristic functions. To do so, we use functions of non-commuting…
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…
