Quantum Financial Modeling on Noisy Intermediate-Scale Quantum Hardware: Random Walks Using Approximate Quantum Counting

Dominic Widdows,
Amit Bhattacharyya

Abstract: Quantum computers are expected to contribute more efficient and accurate ways of modeling economic processes. Quantum hardware is currently available at a relatively small scale, but effective algorithms are limited by the number of logic gates that can be used, before noise from gate inaccuracies tends to dominate results. Some theoretical algorithms that have been proposed and studied for years do not perform well yet on quantum hardware in practice. This encourages the development of suitable alternative al… Show more

“…Recent contributions by Li and Liang (2020) [25] on extending option pricing models, Widdows and Bhattacharyya (2024) [26] on quantum financial modeling, and insights by Evanoff (2009) [27] on globalization and systemic risk further reinforce the transformative potential of quantum finance. Additional perspectives by Gkillas and Longin (2018) [28] on Bitcoin, and by Zhou et al (2019) [29] on marketing agility under market turbulence, alongside a review of evidence for financial contagion (2015) [30], contribute to an understanding of complex economic environments.…”
