Effects of single-qubit quantum noise on entanglement purification
Giuliano Benenti, Sara Felloni, Giuliano Strini
We study the stability under quantum noise effects of the quantum privacy amplification protocol for the purification of entanglement in quantum cryptography. We assume that the E9…
Dissipative quantum chaos: transition from wave packet collapse to explosion
Gabriel G. Carlo, Giuliano Benenti, Dima L. Shepelyansky
Using the quantum trajectories approach we study the quantum dynamics of a dissipative chaotic system described by the Zaslavsky map. For strong dissipation the quantum wave functi…
A model of deterministic detector with dynamical decoherence
Jae Weon Lee, Dmitri V. Averin, Giuliano Benenti +1
We discuss a deterministic model of detector coupled to a two-level system (a qubit). The detector is a quasi-classical object whose dynamics is described by the kicked rotator Ham…
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…
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…
