We study the information dynamics in a network of spin-1/2 particles when edges representing XY interactions are randomly added to a disconnected graph according to a probability distribution characterized by a "weighting" parameter. In this way, we model dissipation of information initially localized in a single or in two qubits all over the network. We then show the dependence of this phenomenon on the weighting parameter and the size of the network.

Abstract
We study the information dynamics in a network of spin-1/2 particles when edges representing XY interactions are randomly added to a disconnected graph according to a probability distribution characterized by a "weighting" parameter. In this way, we model dissipation of information initially localized in a single or in two qubits all over the network. We then show the dependence of this phenomenon on the weighting parameter and the size of the network.File in questo prodotto:
