    "abstract": "We analyze and compare three different strategies, all aimed at controlling\nand eventually halting decoherence. The first strategy hinges upon the quantum\nZeno effect, the second makes use of frequent unitary interruptions\n(\"bang-bang\" pulses and their generalization, quantum dynamical decoupling),\nand the third of a strong, continuous coupling. Decoherence is shown to be\nsuppressed only if the frequency N of the measurements/pulses is large enough\nor if the coupling K is sufficiently strong. Otherwise, if N or K are large,\nbut not extremely large, all these control procedures accelerate decoherence.\nWe investigate the problem in a general setting and then consider some\npractical examples, relevant for quantum computation.",
