Where does this fail? The weak link is the assumption that a 64-qubit test bench on 250 assets is sufficient to validate large-scale portfolio optimization, thus ignoring the true mode of failure in a real environment. A universe of 250 assets is a rough simplification compared to the thousands of financial instruments managed by a global pension fund, not to mention the constraints of liquidity and complex derivatives markets. For example, Norway's Government Pension Fund Global manages thousands of assets, with diversification mandates that far exceed the scope of such current quantum simulation, creating a significant blast radius if this extrapolation is made. Trusting this test as proof of real feasibility is a bridge too far; the attack surface of risks is much broader.
