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…
Chaotic dynamics in superconducting nanocircuits
Simone Montangero, Alessandro Romito, Giuliano Benenti +1
The quantum kicked rotator can be realized in a periodically driven superconducting nanocircuit. A study of the fidelity allows the experimental investigation of exponential instab…
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…
