Towards Quantum Advantage in Financial Market Risk using Quantum Gradient Algorithms [PDF]

open access: yesQuantum, 2022
We introduce a quantum algorithm to compute the market risk of financial derivatives. Previous work has shown that quantum amplitude estimation can accelerate derivative pricing quadratically in the target error and we extend this to a quadratic error ...

Evaluating Quantum Amplitude Estimation for Pricing Multi-Asset Basket Options [PDF]

open access: yes2025 IEEE International Conference on Quantum Artificial Intelligence (QAI)
Accurate and efficient pricing of multi-asset basket options poses a significant challenge, especially when dealing with complex realworld data. In this work, we investigate the role of quantum-enhanced uncertainty modeling in financial pricing options ...

Non-Boolean quantum amplitude amplification and quantum mean estimation

open access: yesQuantum Information Processing, 2023
This paper generalizes the quantum amplitude amplification and amplitude estimation algorithms to work with non-boolean oracles. The action of a non-boolean oracle $U_φ$ on an eigenstate $|x\rangle$ is to apply a state-dependent phase-shift $φ(x)$. Unlike boolean oracles, the eigenvalues $\exp(iφ(x))$ of a non-boolean oracle are not restricted to be ...

A Hybrid Quantum Image-Matching Algorithm

open access: yesEntropy, 2022
Image matching is an important research topic in computer vision and image processing. However, existing quantum algorithms mainly focus on accurate matching between template pixels, and are not robust to changes in image location and scale. In addition,

Average-Case Verification of the Quantum Fourier Transform Enables Worst-Case Phase Estimation [PDF]

open access: yesQuantum, 2022
The quantum Fourier transform (QFT) is a key primitive for quantum computing that is typically used as a subroutine within a larger computation, for instance for phase estimation.

Random-depth Quantum Amplitude Estimation

open access: yes, 2023
The maximum likelihood amplitude estimation algorithm (MLAE) is a practical solution to the quantum amplitude estimation problem with Heisenberg limit error convergence. We improve MLAE by using random depths to avoid the so-called critical points, and do numerical experiments to show that our algorithm is approximately unbiased compared to the ...

Quantum Algorithms for Anomaly Detection Using Amplitude Estimation

open access: yesSSRN Electronic Journal, 2022
Anomaly detection plays a critical role in fraud detection, health care, intrusion detection, military surveillance, etc. Anomaly detection algorithm based on density estimation (called ADDE algorithm) is one of widely used algorithms. Liang et al. proposed a quantum version of the ADDE algorithm [Phys. Rev. A 99, 052310 (2019)] and it is believed that
