Abstract

How can the electric noise in the vicinity of a metallic body be measured and understood? Trapped ions, known as unique tools for metrology and quantum information processing, also constitute very sensitive probes of this electric noise for distances from micrometers to millimeters. This paper presents various models for the origin of the electric noise, provides a critical review of the experimental findings, and summarizes the important questions that are still open in this active research area.

  • The corresponding electric-field spectral noise density for the axial mode is lower than any comparable measurement in a trap of similar size.

    “The corresponding electric-field spectral noise density for the axial mode, , is lower than any comparable measurement in a trap of similar size46,47.”

    From Penning micro-trap for quantum computing (2024) · cites this paper as [47]

    The review compares electric-field noise measurements across traps of different sizes, including axial-mode measurements (section 1, Frequency scaling at room temperature; page unavailable). It provides a basis for comparison, but the cited passages do not identify the citing paper’s corresponding measurement or establish that it is lower than every comparable measurement in a similarly sized trap.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
