Control of decoherence with no control.
Ontology highlight
ABSTRACT: A common philosophy in control theory is the control of disorder by order. Control of decoherence 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 suppression of decoherence can be achieved using the most disordered white noise field, specifically a white Poissonian noise field. This phenomenon seems to be another anomaly in quantum mechanics and may offer a new strategy in quantum control practices.
