    "abstract": "We demonstrate the advantages of randomization in coherent quantum dynamical\ncontrol. For systems which are either time-varying or require decoupling cycles\ninvolving a large number of operations, we find that simple randomized\nprotocols offer superior convergence and stability as compared to deterministic\ncounterparts. In addition, we show how randomization always allows to\noutperform purely deterministic schemes at long times, including combinatorial\nand concatenated methods. General criteria for optimally interpolating between\ndeterministic and stochastic design are proposed and illustrated in explicit\ndecoupling scenarios relevant to quantum information storage.",
