Quantum Quasi-Monte Carlo: a window for pre-asymptotic quantum advantage
A preprint on arXiv studies quantum quasi-Monte Carlo as a candidate for pre-asymptotic quantum advantage. The abstract frames numerical integration, including financial derivative pricing and risk management, as a setting where classical Monte Carlo's evaluation count to reach a target accuracy is expensive.

If the paper identifies regimes with low qubit and query overhead, it could prompt near-term demonstrations of quantum Monte Carlo speedups on low-dimensional financial integration problems using error-mitigated superconducting or trapped-ion processors.
Pre-asymptotic advantage requires beating classical Monte Carlo only at finite problem sizes, not in the asymptotic limit. NISQ devices may be able to reach that threshold for low-dimensional integrals if the algorithm's circuit depth and error mitigation overhead remain manageable. This depends on the resource estimates the preprint derives, which are not yet stated in the abstract, so the path is plausible but unconfirmed.
