Abstract :
We review our work concerning a method of decoherence control via concatenated dynamical decoupling (DD) pulses. These recursively nested DD pulse sequences exhibit a fault-tolerance threshold similar to that of concatenated quantum error correcting codes. We briefly discuss how quantum logic gates can be incorporated into this framework.
