    "abstract": "We present a general control-theoretic framework for constructing and\nanalyzing random decoupling schemes, applicable to quantum dynamical control of\narbitrary finite-dimensional composite systems. The basic idea is to design the\ncontrol propagator according to a random rather than deterministic path on a\ngroup. We characterize the performance of random decoupling protocols, and\nidentify control scenarios where they can significantly weaken time scale\nrequirements as compared to cyclic counterparts. Implications for reliable\nquantum computation are discussed.",
