Fig. 2: Comparison of the CS and LBCS measurement schemes for the measurement of the initialization state for the S0 Hamiltonian in the various system sizes.

The plots include a black dashed line, which indicates the exact initialization energy as a reference. The shaded region represents the standard error, computed using the variance of the repeated settings estimator in Eq. (6).
