Entanglement-Enhanced Optical Ion Clock
Fig. 2, panel (1)
Contrast of measurement signal against interrogation time (ms) for enDFS (red), ccDFS (blue) and single-ion Ramsey (black), with error bars. Dash-dotted and dotted curves are the lifetime-limited contrast for enDFS and ccDFS; the black curve is a Gaussian noise model. The printed axis break between about 4 and 50 ms is not kept, and the open ccDFS marker at 3.5 ms is drawn filled.

Provenance
This panel was computed from the authors' public data deposit (Zenodo: https://doi.org/10.5281/zenodo.15705557, CC BY 4.0), with the single-ion Ramsey points and the model curves recovered from the published vector figure. The plot shown here is re-rendered for interactive viewing and analysis. See the paper for the original figure and full scientific context.
