What is recorded here?
An aluminium-ion optical clock combined quantum-logic readout, a one-second interrogation enabled by a remote cavity-stabilized laser, and an improved trap and vacuum system. The authors report fractional systematic uncertainty of 5.5 × 10⁻¹⁹ and fractional instability of 3.5 × 10⁻¹⁶/√(τ/s), estimated by comparison with a strontium lattice clock.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The instability is a fitted comparison stability beyond the reported servo time, while 5.5 × 10⁻¹⁹ is the authors’ systematic uncertainty budget. In v1 the clock-operation passage says 26Mg+; v2 corrects that passage to 25Mg+, consistent with its abstract and supplement, but a separate v2 passage still says 27Mg+ for preparation/readout. The precise resolution of the residual inconsistent label remains unverified; avoid an unconditional isotope-specific claim. Their collision-shift figures differ slightly by rounding or version within the same manuscript: main text reports −(0.25 ± 0.36)×10⁻¹⁹ and the supplement reports −(0.26 ± 0.37)×10⁻¹⁹. Both are conditional estimates; no independent recalculation was performed.
