ABSTRACT
Quantum computing and quantum machines continue to raise awareness once people realized that “Nature isn’t classical. If you want to make a simulation of nature, you’d better make it quantum mechanical.” (Feynman, 1982). On the other hand, as the Internet brings big data, machine learning has become a logical step for researchers looking for tasks such as the patterns behind the data, or for companies seeking to maximize their data’s potential value. The combination of the quantum computing and machine learning (ML) fields has resulted in quantum machine learning (QML), one of today’s most active fields. This preview provides essential concepts in quantum computation, including the basic quantum physics and fundamentals of quantum computing. The next section examines quantum-enhanced ML models and algorithms. The current state of knowledge of applications is discussed in the following section and the preview concludes with open questions for future research on QML.
