Non-Markovian signatures in the current noise of a charge qubit

Alessandro Braggio, Christian Flindt, Tomas Novotny

Published 2008-01-24Version 1

We investigate the current noise of a charge qubit coupled to a phonon bath in different parameter regimes. We find, using the theory of Full Counting Statistics of non-Markovian systems, that the current fluctuations are strongly influenced by memory effects generated from the interplay between quantum coherence and the dynamics of the phonon bath.
