| dc.description | Quantum information processing systems are often operated through time dependent controls; choosing these controls in a way that makes the resulting operation insensitive to variations in unknown or uncontrollable system parameters is an important prerequisite for obtaining high-fidelity gate operations. In this article we present a numerical method for constructing such robust control sequences for a quite general class of quantum information processing systems. As an application of the method we have designed a robust implementation of a phase-shift operation central to rare earth quantum computing, an ensemble quantum computing system proposed by Ohlsson et. al. [Opt. Comm. 201, 71 (2002)]. In this case the method has been used to obtain a high degree of insensitivity with respect to differences between ensemble members, but it is equally well suited for quantum computing with a single physical system. | |
