AI Summary

This study addresses the stringent demands for accuracy, efficiency, and robustness in real-time forecasting within highly dynamic financial markets by introducing, for the first time, a quantum-inspired neural network architecture that integrates qubit and qutrit representations for financial time series modeling. The proposed framework incorporates a tailored training protocol specifically designed for this hybrid quantum representation. Empirical evaluations demonstrate that the method achieves over 70% prediction accuracy on stock forecasting tasks and consistently outperforms both classical artificial neural networks and pure qubit-based quantum networks across multiple performance metrics, including Sharpe ratio, information coefficient, and prediction consistency. Moreover, the approach significantly reduces training time, thereby achieving a synergistic improvement in both predictive performance and computational efficiency.

Abstract

This research investigates the performance and efficacy of machine learning models in stock prediction, comparing Artificial Neural Networks (ANNs), Quantum Qubit-based Neural Networks (QQBNs), and Quantum Qutrit-based Neural Networks (QQTNs). By outlining methodologies, architectures, and training procedures, the study highlights significant differences in training times and performance metrics across models. While all models demonstrate robust accuracies above 70%, the Quantum Qutrit-based Neural Network consistently outperforms with advantages in risk-adjusted returns, measured by the Sharpe ratio, greater consistency in prediction quality through the Information Coefficient, and enhanced robustness under varying market conditions. The QQTN not only surpasses its classical and qubit-based counterparts in multiple quantitative and qualitative metrics but also achieves comparable performance with significantly reduced training times. These results showcase the promising prospects of Quantum Qutrit-based Neural Networks in practical financial applications, where real-time processing is critical. By achieving superior accuracy, efficiency, and adaptability, the proposed models underscore the transformative potential of quantum-inspired approaches, paving the way for their integration into computationally intensive fields.
