  We discuss the effect of correlated noise on the robustness of quantum
coherent phenomena. First we consider a simple, toy model to illustrate the
effect of such correlations on the decoherence process. Then we show how
decoherence rates can be suppressed using a Parrondo-like effect. Finally, we
report the results of many-body calculations in which an
experimentally-measurable quantum coherence phenomenon is significantly
enhanced by non-Markovian dynamics arising from the noise source.
