    "abstract": "Minimizing the effect of decoherence on a quantum register must be a central\npart of any strategy to realize scalable quantum information processing. Apart\nfrom the strength of the coupling to the environment, the decoherence rate is\ndetermined by the the system level structure and by the spectral composition of\nthe noise trace that the environment generates. Here, we discuss a relatively\nsimple model that allows us to study these different effects quantitatively in\ndetail. We evaluate the effect that the perturbation has on an NMR system while\nit performs a Grover search algorithm.",
