摘要：A major challenge in the implementation of quantum computers is mitigating the impact of undesired couplings with the environment that lead to decoherence. Here, we discuss an error-avoiding strategy that is based upon freedoms inherent in decomposing a quantum algorithm into fundamental gates. Although this approach is specific to a particular algorithm and a collective noise model, it does not the require complicated encodings or significant additional qubit resources of more general error-correcting codes. This paper also includes an overview of quantum computation, including a discussion of the quantum search algorithm.
