Eigenstates of Operating Quantum Computer: Hypersensitivity to Static Imperfections
Giuliano Benenti, Giulio Casati, Simone Montangero +1
We study the properties of eigenstates of an operating quantum computer which simulates the dynamical evolution in the regime of quantum chaos. Even if the quantum algorithm is pol…

Sensitivity of Quantum Motion for Classically Chaotic Systems
Giuliano Benenti, Giulio Casati
We discuss the behavior of fidelity for a classically chaotic quantum system in the metallic regime. We show the existence of a critical value of the perturbation below which the e…
