Abstract

We present the principles of universal dynamical control of open quantum systems aimed at optimally suppressing their decoherence. Several basic scenarios of this control are discussed. Our results indicate that very limited knowledge regarding the system-environment correlation is sufficient to implement control that would suppress decoherence and bring out quantum behavior in complex macroscopic systems that are embedded in thermal noisy environments.
