Decoherence induced by a dynamic spin environment: The universal regime

Mostrar todas las versiones(2)

This paper analyzes the decoherence induced on a single qubit by the interaction with a spin chain with nontrivial internal dynamics (XY -type interactions). The aim of the paper is to study the existence and properties of the so-called universal regime, in which the decoherence time scale becomes i...
