    "abstract": "The problem of the quantitative degradation of the performance of a quantum\ncomputer due to noisy unitary gates (imperfect external control) is studied. It\nis shown that quite general conclusions on the evolution of the fidelity can be\nreached by using the conjecture that the set of states visited by a quantum\nalgorithm can be replaced by the uniform (Haar) ensemble. These general results\nare tested numerically against quantum computer simulations of two particular\nperiodically driven quantum systems.",
