Quantum Advantage on Machine Learning Models

In recent years, quantum computers have become one of most attractive machines based on the principles of quantum mechanics. We make use of quantum superposition, quantum entanglement and so on in the calculation process. Expectations have increased enormously since the announcement of Quantum supremacy1, 2 in October 2019 and December 2020 by superconducting and photonic quantum computers. There are three types of quantum computing devices: quantum annealing3, quantum gates and optical Continuous-Variable2, 4. Quantum gate quantum computing devices include the superconducting type5, 6, trapped ion type7, 8, semiconductor quantum type9, 10, diamond NV centre type11 and Rydberg atom type12. The performance of quantum devices has been rapidly improving day by day in recent years because of severe development competition.
