    "abstract": "Quantum computers will be unique tools for understanding complex quantum\nsystems. We report an experimental implementation of a sensitive, quantum\ncoherence-dependent localization phenomenon on a quantum information processor\n(QIP). The localization effect was studied by emulating the dynamics of the\nquantum sawtooth map in the perturbative regime on a three-qubit QIP. Our\nresults show that the width of the probability distribution in momentum space\nremained essentially unchanged with successive iterations of the sawtooth map,\na result that is consistent with localization. The height of the peak relative\nto the baseline of the probability distribution did change, a result that is\nconsistent with our QIP being an ensemble of quantum systems with a\ndistribution of errors over the ensemble. We further show that the previously\nmeasured distributions of control errors correctly account for the observed\nchanges in the probability distribution.",
