Abstract

This paper presents an identification model based on quantum neural network for engineering systems. Quantum neural network (QNN) is a superior strategy to improve the computational efficiency for conventional neural network structures due to their unprecedented computation capabilities. The structure of identification model consists of multi-layer QNN in which qubit neurons are used for data processing. The identification model stability is ensured by introducing a learning algorithm based on Lyapunov theorem for online tuning of the QNN. Furthermore, the convergence and stability of the identification structure are accelerated with developing adaptive learning rates based on Lyapunov theory. The effectiveness of the developed identification model is confirmed with introducing it for two engineering processes and comparing its modeling results with other structures. Simulation results reflect the high superior performance of the developed model compared with other approaches.

Controller Application of a Multi-Layer Quantum Neural Network with Qubit Neurons

Kazuhiko Takahashi, Motoki Kurokawa, Masafumi Hashimoto

This paper investigates a quantum neural network and discusses its application in control systems. A learning-type neural network-based controller that uses a multi-layer quantum neural network having qubit neurons as its information processing unit is proposed. Three learning algorithms; a back-propagation algorithm, a conjugate gradient algorithm and a real-coded genetic algorithm, are investigated to supervise the training of the multi-layer quantum neural network. To evaluate the learning performance and the capability of the quantum neural network-based controller, we conducted computational experiments for controlling a nonlinear discrete-time plant and a nonholonomic system - in this study a two-wheeled robot. The results of computational experiments confirm both the feasibility and the effectiveness of the quantum neural network-based controller and that the real-coded genetic algorithm is suitable for the learning method of the quantum neural network-based controller.

Quantum Neural Networks (QNNs) represent a promising paradigm shift in machine learning, leveraging the unique properties of quantum mechanics to potentially surpass classical neural networks. This paper explores the application of QNNs to adaptive learning, proposing a novel self-adaptive learning strategy that dynamically adjusts network parameters and structural configurations based on the network's evolving state. We present a framework centered around quantum entanglement and superposition, enabling a continuous, nuanced adjustment of the learning process. The core mechanism focuses on leveraging the inherent quantum properties to optimize learning efficiency. We demonstrate the efficacy of this approach through simulations and preliminary experiments, illustrating a significant improvement in learning speed and robustness compared to traditional approaches. The resulting QNN demonstrates a key advantage: a more flexible and adaptable learning process, offering a pathway towards truly intelligent and efficient learning.
