Decoupling quantum dynamics in a detected-jump correcting code — •Daniel Geberth and Gernot Alber — Institut für Angewandte Physik, TU Darmstadt, 64289 Darmstadt

The dominating goal in practical quantum information is attaining the highest possible fidelity over long times of computation or storage. A concatenated error correction method consisting of an error correcting code to address spontaneous emission and a decoupling scheme to weaken the effects of coherent couplings are presented. Limitations on the choice and strength of the decoupling operators and the resulting attainable fidelity decay rates are discussed.
