Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems. To optimize the performance of QIP systems or quantum computers in terms of both fidelity and algorithm uptime or throughput, described are techniques to stabilize continuous and discrete errors from drifting and/or noisy secondary observables to achieve long term stable operation.

Abstract: Techniques to address the problem of having micromotion and stray fields affect trapped ions and the operation of QIP systems based on trapped ions are described. For example, one technique or approach may involve collecting scattered photons off the ions using a resonant or near-resonant oscillating electric field (e.g., a laser beam or a microwave source) with some projection in the axis or direction of micromotion that one wishes to reduce. Another technique or approach may include raising and lowering the trapping potentials to see how the ion position changes. The information collected from these techniques may be used to provide appropriate adjustments. Accordingly, the present disclosure describes methods, scripts, or techniques that minimize the effects of micromotion.
