    • We could also detect the qubits separately. In the case of one ancilla, the total error is not reduced, but if the separate answers disagree, it can be considered as a detected error. If the part of the computation leading to this detected error can be discarded and recomputed until the answers agree, then the net error is reduced [2].

    • Small ion separations are desirable because logic-gate durations are reduced as the confinement strength increases.

    • The background noise can be added by adjusting the level of detected stray scattered light, but we found it more convenient for the purpose of our demonstration to add it numerically.
