Figure 4

Boxplot of the average deviation between results of 2D classical FT and QFT depending on matrix size (A). The red line indicates the average deviation expected when all states are measured with equal probability. Numerically generated test scatterer (B) and reconstruction on a real quantum computer (C) as well as on a quantum simulator backend (E). While all calculations (C) and (D) reconstructed a 3D volume only slices through this volume are shown for clarity.
