Entanglement dynamics and relaxation in a few qubit system interacting with random collisions
Giuseppe Gennaro, Giuliano Benenti, Massimo Palma
The dynamics of a single qubit interacting by a sequence of pairwise collisions with an environment consisting of just two more qubits is analyzed. Each collision is modeled in ter…
Memory effects in quantum information transmission across a Hamiltonian dephasing channel
A. D'Arrigo, G. Benenti, G. Falci
We study a dephasing channel with memory, modelled by a multimode environment of oscillators. Focusing on the case of two channel uses, we show that memory effects can enhance the…
Quantum simulation of the single-particle Schrodinger equation
Giuliano Benenti, Giuliano Strini
The working of a quantum computer is described in the concrete example of a quantum simulator of the single-particle Schrodinger equation. We show that a register of 6-10 qubits is…
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…
Coherent imaging with pseudo-thermal incoherent light
A. Gatti, M. Bache, D. Magatti +3
We investigate experimentally fundamental properties of coherent ghost imaging using spatially incoherent beams generated from a pseudo-thermal source. A complementarity between th…
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…
