Quantum-enhanced multiparameter sensing in a single mode
Fig. 2, panel (a-3)
Experimentally reconstructed characteristic function $\mathrm{Re}[\chi(\beta)]$ of the grid state with target $\Delta = 0.30$, against $\mathrm{Re}[\beta]/\sqrt{\pi}$ and $\mathrm{Im}[\beta]/\sqrt{\pi}$, on a 49 by 49 grid. Map (iii) of panel (a), with crosses at the points that give the visibilities $\eta_x$ (at $i\sqrt{\pi}$) and $\eta_p$ (at $-\sqrt{\pi}$).
