Fig. 9, panel (b)

Measured one-dimensional Wigner slices $W(0,\beta_2)$ against $\mathrm{Re}(\beta_2)$ at three instances: A1 after preparation (crosses), A2 after 10 ms of thermalization (circles) and A3 after parity-based postselection (squares), with spin-projection noise error bars. The dotted, dashed and solid curves are the numerical-simulation results for A1, A2 and A3.
