Abstract:
We consider a recently introduced framework for the description of memory effects basedon quantum state distinguishability quantifiers, in which entropic quantifiers can beincluded. After briefly presenting the approach, we validate it considering the perfor-mance of different quantifiers in the characterization of the reduced dynamics of a two-level system undergoing decoherence. We investigate the different behaviors of thesequantifiers in the dependence on physical features of the model, such as environmentaltemperature and coupling strength. It appears that the performance of the differentquantifiers conveys the same physical information, though with different sensitivities,thus supporting robustness of the approach.
