    • Note that in the presence of small noncyclic perturbations the gate operator 3 may be modified as (Formula presented) with (Formula presented) ((Formula presented)) the visibility being slightly less than unit, which may lead to a weak decoherence effect; but it is negligible, even inevitable. Quantitatively, for a small deviation (Formula presented) from the period (Formula presented), (Formula presented) is estimated to be (Formula presented) and the deviation of (Formula presented) is about (Formula presented)
