Complexity of Quantum States and Reversibility of Quantum Motion
Valentin V. Sokolov, Oleg V. Zhirov, Giuliano Benenti +1
We present a quantitative analysis of the reversibility properties of classically chaotic quantum motion. We analyze the connection between reversibility and the rate at which a qu…
Memory effects in a Markov chain dephasing channel
Antonio D'Arrigo, Elena De Leo, Giuliano Benenti +1
We study a dephasing channel with memory, modelled by a Markov chain. We show that even weak memory effects have a detrimental impact on the performance of quantum error correcting…
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…
