Entanglement-Enhanced Optical Ion Clock
Fig. 3, panel (1)
Fractional stability of the $^{40}\mathrm{Ca}^+/^{87}\mathrm{Sr}$ frequency ratio, OADEV $\sigma_y$ against averaging time $\tau$ (s), at 50 ms interrogation time for the enDFS (red) and ccDFS (blue) schemes. Filled markers are the data range taken for the stability fit, open markers the rest. Error bars are smaller than the symbols and are not drawn.
