Fig. 1: Ground-state energy errors with respect to the extrapolated CBS limit.
From: Shortcut to chemically accurate quantum computing via density-based basis-set correction

Outside the green box: ADAPT-VQE calculations. Inside the green box: FCI calculations from a classical computer. Dot markers correspond to energies without basis-set corrections. Cross markers correspond to energies corrected with Strategy 1 [Eq. (6)]. On the x-axis, the labels \({{\mathcal{B}}}+\) symbolize basis-set corrected values. The blue box corresponds to a range of 1.6 mHa around the extrapolated CBS limit. The errors for each ADAPT-VQE computation with respect to the FCI energy for a given basis set are reported in the SI.
