The research of quantum machine learning is an emerging field that has flourished with the rapid development of quantum computing. In particular, quantum neural networks (QNNs), similar to classical neural networks, have already been applied in many large-scale machine learning tasks such as automatic speech recognition, speech enhancement, and natural language understanding. Despite the hardware limitation on noisy intermediate-scale quantum (NISQ) devices (5–50 qubits), the QNN based deep architectures, such as a randomized quantum convolutional neural network (QCNN) and variational quantum circuit (VQC), can be set up to attain competitive empirical results in experiments of speech and language processing. Moreover, more secured data privacy can be ensured by applying QNN based models.

Through IJCAI’s flagship and influence in AI research, we believe this tutorial can create the synergies and reinforce the momentum in advanced research and novel applications based on quantum computing and machine learning. This tutorial will provide an overview of the fundamentals of quantum mechanics, quantum machine learning and quantum neural networks. Then, we introduce the related applications in speech recognition and natural language understanding. In more detail, in the introduction part, we briefly introduce basic concepts of quantum computing, quantum mechanics and necessary multi-linear algebra associated with quantum technology. In the second section, we will discuss QNNs, especially based on variational quantum circuits (VQC) for QNNs. Finally, we provide several examples of employing VQC-QNN for speech recognition and natural language understanding.
