    "abstract": "The dynamics of a decohering two-level system driven by a suitable control\nHamiltonian is studied. The control procedure is implemented as a sequence of\nradiofrequency pulses that repetitively flip the state of the system, a\ntechnique that can be termed quantum \"bang-bang\" control after its classical\nanalog. Decoherence introduced by the system\u0027s interaction with a quantum\nenvironment is shown to be washed out completely in the limit of continuous\nflipping and greatly suppressed provided the interval between the pulses is\nmade comparable to the correlation time of the environment. The model suggests\na strategy to fight against decoherence that complements existing quantum\nerror-correction techniques.",
