Dynamical decoupling of open quantum systems. (English) Zbl 1042.81524

Phys. Rev. Lett. 82, No. 12, 2417-2421 (1999).
Summary: We propose a novel dynamical method for beating decoherence and dissipation in open quantum systems. We demonstrate the possibility of filtering out the effects of unwanted (not necessarily known) system-environment interactions and show that the noise-suppression procedure can be combined with the capability of retaining control over the effective dynamical evolution of the open quantum system. Implications for quantum information processing are discussed.
