Fig. 3: Comparison of experimental results on the superconducting quantum processor with the ideal ones for the 2D vortex.

Vorticity contours are depicted for (a) the exact solution and (b) the experimental result. Streamlines are color-coded by velocity magnitude. c Comparison of 〈ω〉θ at t = 0, π/4, and π/2 (dashed lines: exact solution; circles: experimental result with error bars denoting one standard deviation), where 〈ω〉θ denotes the vorticity averaged over the θ-direction in polar coordinates (r, θ). The data is obtained with 105 measurement shots, and the experiment is repeated for five times.
