Extended Data Fig. 4: State-preparation errors for 2D array.

a, Population measurement for a FM state (red) with a single hole |h⟩ (white) at the centre. b, Population measurement for a Néel-ordered state alternating between |↑⟩ (blue) and |↓⟩ (red) with a central hole. The pie charts at each site show the relative populations of the four possible states: ground state (black), |↓⟩ (red), |h⟩ (white) and |↑⟩ (blue). Detection errors have been corrected using a maximum likelihood estimation method. The observed state-preparation fidelities are incorporated into the numerical simulations presented in the main text.
