Figure shows the dependence of the calculation time on the dimensionality of the model, from the 2D model (with 0BM) to the 2D + 23BM model. Aside from a slight deviation for the 2D + 12BM simulation, which is probably due to input/output at a maximum total shared bandwidth of 119 MB/s, it appears clear that the computational cost of CT-TSH grows linearly with the number of (nuclear/classical) degrees of freedom, while TSH-ED is basically independent. Therefore, the limiting step in CT-TSH appears to be the calculation of the quantum momentum, which is not performed in TSH-ED.
