Raman Scattering Errors in Stimulated-Raman-Induced Logic Gates in Ba+133
Open accessAbstract
^{133}Ba^{+} is illuminated by a laser that is far detuned from optical transitions, and the resulting spontaneous Raman scattering rate is measured. The observed scattering rate is lower than previous theoretical estimates. The majority of the discrepancy is explained by a more accurate treatment of the scattered photon density of states. This work establishes that, contrary to previous models, there is no fundamental atomic physics limit to laser-driven quantum gates from laser-induced spontaneous Raman scattering.

The accumulation of physical errors prevents the execution of large-scale algorithms in current quantum computers.
“The accumulation of physical errors1–3 prevents the execution of large-scale algorithms in current quantum computers.”
From High-threshold and low-overhead fault-tolerant quantum memory (2024) · cites this paper as [2]
The opening discussion (p. 1) says that even the highest-fidelity trapped-ion gates remain below estimated thresholds for practical fault-tolerant quantum computers. This supports the general concern about physical errors, but the paper does not establish that accumulated errors prevent large-scale algorithms across current quantum computers generally.

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.
