Non-Markovian signatures in the current noise of a charge qubit
arXiv:0801.3723 · doi:10.1016/j.physe.2007.10.082
Abstract
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.
