Principle and State-of-Art Applications of Quantum Computing

Contemporarily, the classical computing has met the upper limitations of Moore’s law due to the restrictions of the resolution for light sourcing and material. On this basis, the quantum computing has been rapidly developed due to the advantages of parallel computation, which is able to be faster more than 3 orders of magnitude than conventional computer in some issues. With this in mind, this study discusses the basic principles of quantum computing as well as the corresponding state-of-art applications. To be specific, the developing history of the quantum computing is briefly introduced. Subsequently, the entanglement principle will be demonstrated accordingly. Afterwards, three types of the state-of-art quantum computing facilities will be demonstrated. Then, some of the applications and common algorithms will be discussed simultaneously. According to the analysis, the limitations and defects of current investigation of quantum computing will be illustrated. In conclusion, these outcomes provided guideline for further exploration of quantum computing.
