The proposed pipeline includes not only Iterative-QAOA but also graph reduction for handling large graphs and a classical FM refinement that further improves the obtained solution. Therefore, even if the proposed pipeline is up to 14.6% faster than the baseline, this comparison alone cannot isolate how much of that difference is attributable specifically to QAOA.

✍️ Quantum Index Analysis

Interpreting the 14.6% figure directly as the “speedup due to quantum computing” can be misleading. The acceleration demonstrated here is not the computation on the quantum computer itself, but the result of introducing a new preprocessing flow that includes quantum algorithms into the end-to-end workflow that uses LS-DYNA.

The quantum algorithms were applied to graph partitioning before solving large systems of linear equations. Better partitioning reduces extra computation and memory use incurred by downstream classical solvers. Simplifying the comparison yields the following:

• Baseline workflow evaluated in this study:
  LS-GPart → LS-DYNA

• Proposed workflow in this study:
  Graph reduction → Iterative-QAOA → classical FM refinement → remaining processing by LS-GPart → LS-DYNA

What matters here is that this is not a simple ‘‘classical algorithm versus quantum algorithm’’ comparison. The proposed pipeline includes not only Iterative-QAOA but also graph reduction for handling large graphs and a classical FM refinement that further improves the obtained solution. Therefore, even if the proposed pipeline is up to 14.6% faster than the baseline, this comparison alone cannot isolate how much of that difference is attributable specifically to QAOA.

At the same time, the baseline is not ‘‘LS-DYNA with no optimization.’’ The baseline includes LS-GPart, a classical graph partitioning method used with LS-DYNA, so showing an end-to-end runtime reduction relative to the existing workflow that includes LS-GPart is meaningful. The value of this research lies in verifying effects through to the actual CAE pipeline rather than benchmarking a standalone quantum algorithm.

Only if the QAOA-containing configuration outperforms such a classical alternative can one more convincingly argue for the contribution of the quantum component itself.

Therefore, what has been demonstrated here is that a hybrid preprocessing approach including quantum components can speed up an LS-DYNA workflow end-to-end by up to 14.6%, and not that a quantum algorithm alone achieved a 14.6% speedup.
