    "abstract": "Quantum information processing systems are often operated through time\ndependent controls; choosing these controls in a way that makes the resulting\noperation insensitive to variations in unknown or uncontrollable system\nparameters is an important prerequisite for obtaining high-fidelity gate\noperations. In this article we present a numerical method for constructing such\nrobust control sequences for a quite general class of quantum information\nprocessing systems. As an application of the method we have designed a robust\nimplementation of a phase-shift operation central to rare earth quantum\ncomputing, an ensemble quantum computing system proposed by Ohlsson et. al.\n[Opt. Comm. 201, 71 (2002)]. In this case the method has been used to obtain a\nhigh degree of insensitivity with respect to differences between ensemble\nmembers, but it is equally well suited for quantum computing with a single\nphysical system.",
