With the rapid development of science and technology, people tend to have a higher demand for computing. Classical computers can no longer meet part of the computing needs, so quantum information systems have gained more and more attention. Quantum computers have good parallelism, fast information processing speed, large amount of information storage, and performance in many fields far surpasses classical computers. In this article, the author introduces coherent superposition and part of quantum gates and quantum algorithms meanwhile compares classical computers with quantum computers in many aspects. The advantages and disadvantages of quantum computers in principle are also drawn out. Finally, the author proposes future prospects for quantum computers prediction.
