摘要:

本文介绍了一个端到端框架,用于多资产期权定价,该框架结合了市场一致的风险中性密度恢复与量子加速的数值积分。我们首先利用正态逆高斯(NIG)模型从欧洲期权报价中校准无套利边缘分布,利用其分析可处理性和捕捉偏度和厚尾的能力。边缘分布通过高斯共轭耦合以构建联合分布。为了解决高维积分所需计算瓶颈,我们采用基于量子振幅估计(QAE)的量子加速蒙特卡洛(QAMC)技术,实现比经典蒙特卡洛(CMC)方法有二次收敛改进。理论结果建立了边缘密度估计(通过余弦级数展开)和多维定价的准确性和查询复杂度。对流动性良好的权益实体(Credit Agricole、AXA、Michelin)的实证测试证实了高校准精度,并展示了QAMC在可比精度下需要比经典方法少10-100次查询。本研究提供了一种将无套利建模与量子计算结合的实用途径,突显了可扩展性和未来扩展到复杂衍生品的含义。

英文摘要:

This work introduces an end-to-end framework for multi-asset option pricing that combines market-consistent risk-neutral density recovery with quantum-accelerated numerical integration. We first calibrate arbitrage-free marginal distributions from European option quotes using the Normal Inverse Gaussian (NIG) model, leveraging its analytical tractability and ability to capture skewness and fat tails. Marginals are coupled via a Gaussian copula to construct joint distributions. To address the computational bottleneck of the high-dimensional integration required to solve the option pricing formula, we employ Quantum Accelerated Monte Carlo (QAMC) techniques based on Quantum Amplitude Estimation (QAE), achieving quadratic convergence improvements over classical Monte Carlo (CMC) methods. Theoretical results establish accuracy bounds and query complexity for both marginal density estimation (via cosine-series expansions) and multidimensional pricing. Empirical tests on liquid equity entities (Credit Agricole, AXA, Michelin) confirm high calibration accuracy and demonstrate that QAMC requires 10-100 times fewer queries than classical methods for comparable precision. This study provides a practical route to integrate arbitrage-aware modelling with quantum computing, highlighting implications for scalability and future extensions to complex derivatives.
