A common philosophy in control theory is the control of disorder by order. Control of open system dynamics is no exception; strategies aimed at suppressing quantum decoherence adopt this point of view. Here we predict an anomalous phenomenon in open quantum systems-control of disorder by (even more) disorder. It is shown that the most disordered white noise field, specifically a white Poissonian noise field, might be used to induce the adiabaticity and suppress the decoherence of the system. This phenomenon seems to be another anomaly in quantum mechanics and may offer a new strategy in quantum control practices.
