  Quantum Computing (QC) claims to improve the efficiency of solving complex
problems, compared to classical computing. When QC is applied to Machine
Learning (ML) applications, it forms a Quantum Machine Learning (QML) system.
After discussing the basic concepts of QC and its advantages over classical
computing, this paper reviews the key aspects of QML in a comprehensive manner.
We discuss different QML algorithms and their domain applicability, quantum
datasets, hardware technologies, software tools, simulators, and applications.
In this survey, we provide valuable information and resources for readers to
jumpstart into the current state-of-the-art techniques in the QML field.
