Entanglement Across a Transition to Quantum Chaos
Carlos Mejia-Monasterio, Giuliano Benenti, Gabriel G. Carlo +1
We study the relation between entanglement and quantum chaos in one- and two-dimensional spin-1/2 lattice models, which exhibit mixing of the noninteracting eigenfunctions and tran…
Universal decay of classical Loschmidt echo of neutrally stable but mixing dynamics
Giulio Casati, Tomaz Prosen, Jinghua Lan +1
We provide analytical and numerical evidence that classical mixing systems which lack exponential sensitivity on initial conditions, exhibit universal decay of Loschmidt echo which…
Quantum ratchets in dissipative chaotic systems
Gabriel G. Carlo, Giuliano Benenti, Giulio Casati +1
Using the method of quantum trajectories we study a quantum chaotic dissipative ratchet appearing for particles in a pulsed asymmetric potential in the presence of a dissipative en…
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…
Simulating noisy quantum protocols with quantum trajectories
Gabriel G. Carlo, Giuliano Benenti, Giulio Casati +1
The theory of quantum trajectories is applied to simulate the effects of quantum noise sources induced by the environment on quantum information protocols. We study two models that…
Quantum computing and information extraction for a dynamical quantum system
Giuliano Benenti, Giulio Casati, Simone Montangero
We discuss the simulation of a complex dynamical system, the so-called quantum sawtooth map model, on a quantum computer. We show that a quantum computer can be used to efficiently…
