The weakness of this approach is that benchmarking portfolio optimization on 250 S&P 500 assets on a 64-qubit system masks a crucial failure mode.
We are talking here about the fundamental difference between a technical demonstration and a operationally viable solution for market finance.
Such a test does not take into account real liquidity constraints, market dynamics, or the resilience needed for Swiss pension funds.
For example, managing multi-billion dollar portfolios requires a scalability and robustness that 64 qubits simply cannot provide in the face of a major market shock; the promise of a snapshot is insufficient.
