Relaxation due to random collisions with a many-qudit environment

Giuseppe Gennaro, Giuliano Benenti, G. Massimo Palma

We analyze the dynamics of a system qudit of dimension mu sequentially interacting with the nu-dimensional qudits of a chain playing the ore of an environment. Each pairwise collis…

Steering Bose-Einstein condensates despite time symmetry

Dario Poletti, Giuliano Benenti, Giulio Casati +2

A Bose-Einstein condensate in an oscillating spatially asymmetric potential is shown to exhibit a directed current for unbiased initial conditions despite time symmetry. This pheno…

Gaussian wave packets in phase space: The Fermi g_F function

Giuliano Benenti, Giuliano Strini

Any pure quantum state can be equivalently represented by means of its wave function psi(q) or of the Fermi function g_F(q,p), with q and p coordinates and conjugate momenta of the…

Optimal purification of a generic n-qudit state

Giuliano Benenti, Giuliano Strini

We propose a quantum algorithm for the purification of a generic mixed state of a -qudit system by using an ancillary -qudit system. The algorithm is optimal in that (i)…

How complex is the quantum motion?

Giuliano Benenti, Giulio Casati

In classical mechanics the complexity of a dynamical system is characterized by the rate of local exponential instability which effaces the memory of initial conditions and leads t…

Entanglement, randomness and chaos

Giuliano Benenti

Entanglement is not only the most intriguing feature of quantum mechanics, but also a key resource in quantum information science. The entanglement content of random pure quantum s…
