[eng] The study of quantum systems from the perspective of Reservoir Computing is a promising
angle that has been increasingly raising interest in the past few years, since our current
technology allowed for the experimental realisation of such systems. This work explores the
relation between the coherence present in the quantum reservoir and its ability to process
information in the context of the resource theory of coherence. For this we take the transversefield Ising model as our reservoir, which we study in its different dynamical regimes as a
function of the intensity of the magnetic field and the disorder present within. We are able to
link the operational regimes of the reservoir with higher values of the coherence, and relate the
dynamics of each phase to its processing capacity. In addition, we perform an analysis of the
robustness of these reservoirs to phase and bit flip noise, which shows that the latter is more
destructive than the former for the system’s ability to process information. Our results also
establish a link between quantum correlations and high-order degrees of nonlinear processing
capacity
