Algorithmic applications and principles of superconducting quantum computers

Abstract

Nowadays, with the continuous progress of science and technology, the role of quantum computers has received more attention and gradually become a part of national strategies. Many countries, such as the United States, China, and Japan, have invested a lot of resources in research and development, striving to make breakthroughs and take the lead in this field, in order to meet the coming of the future computing era. Superconducting quantum computers are the most widely used computers at the moment. Based on the introduction of Josephson junction, the physical principle of superconducting quantum computers, this paper analyses the advantages and disadvantages of multiple quantum bits as well as the algorithms of various quantum gates in superconducting quantum computers. Moreover, the author also looks forward to the development of the related technologies of superconducting quantum computers. Finally, corresponding suggestions are put forward for some current problems.
