Extended Data Fig. 2: Minimum squeezing parameter as a function of atom number N.
From: Scalable spin squeezing in a dipolar Rydberg atom array
The circles and diamonds correspond to raw and corrected data, respectively. The solid coloured lines are power-law fits. The purple shaded region shows the simulations including 97.5 ± 1% (resp. 99 ± 1%) detection efficiency of \(\left|\uparrow \right\rangle \) (resp. \(\left|\downarrow \right\rangle \)). The dashed curves represent the results of simulations of the XY dipolar model without state preparation and measurement errors (grey) and without detection errors only (pink). The dashed black curve represents the exact results for the OAT model. The inaccessible region corresponds to values of the squeezing parameter smaller than 2/(2 + N)2.
