Overview

Computational study demonstrates over 86% accuracy in forecasting market trends for quantum-sector stocks, highlighting the practical viability of small-scale quantum hardware for finance.

Key Points

To develop and evaluate a platform-agnostic quantum reservoir computing framework using a small-scale quantum system to forecast nonlinear financial time series.
Constructed a quantum reservoir computing architecture using a system of up to six interacting qubits.
Trained and evaluated the model on daily closing prices from N=20 publicly traded quantum-sector companies between April 11, 2020, and April 11, 2025, alongside minute-by-minute after-hours trading data from July 7, 2025.
Optimized reservoir parameters for physical execution across diverse quantum hardware architectures, including superconducting circuits and trapped ions.
Achieved directional stock trend (up/down) classification accuracies exceeding 86% under optimal reservoir parameter configurations.
Demonstrated that a small six-qubit reservoir retains sufficient expressive capacity and robustness to capture complex temporal correlations in volatile financial data.
