Entanglement Echoes in Quantum Computation
Davide Rossini, Giuliano Benenti, Giulio Casati
We study the stability of entanglement in a quantum computer implementing an efficient quantum algorithm, which simulates a quantum chaotic dynamics. For this purpose, we perform a…
Teleportation in a noisy environment: a quantum trajectories approach
Gabriel G Carlo, Giuliano Benenti, Giulio Casati
We study the fidelity of quantum teleportation for the situation in which quantum logic gates are used to provide the long distance entanglement required in the protocol, and where…
Decay of the classical Loschmidt echo in integrable systems
Giuliano Benenti, Giulio Casati, Gregor Veble
We study both analytically and numerically the decay of fidelity of classical motion for integrable systems. We find that the decay can exhibit two qualitatively different behavior…
