Abstract
This paper is a literature review on quantum computing. It presents a comprehensive overview of the history of quantum computing, including its origins in quantum mechanics. It also presents an overview on how quantum computing works, from qubits to quantum gates and circuits. Three subfields of quantum computing (quantum information science, quantum cryptography, and quantum machine learning) are discussed to provide more insight into the real-world applications of quantum computing. Lastly, the paper discusses the future of quantum computing and current research being done to further the field.
