Fig. 3, panel (a)

Quantum Fisher information density $f_{\mathrm{Q}}$ of Ce$_3$Pd$_{20}$Si$_6$ against temperature: $B = 1.73$ T at $\mathbf{q} = (0\bar{1}0)$ (black) and one point at $B = 5.8$ T, $\mathbf{q} = (100)$ (blue), with error bars, and the line drawn through the 1.73 T points in the print.
