Superconducting Quantum Computing

Timothy P. Spiller

Superconducting circuits provide one of the numerous current candidate routes for the realization of quantum computing (QC) technology. In this paper I review the basic physics behind this candidature and outline some superconducting QC proposals currently on the table, demonstrating their common origins. More detailed discussion of the proposals follows, assessing how they measure up to the “DiVincenzo checklist” for QC realizations and the current status of experiments.

Abstract Nowadays the quantum computer has been drawing public attention, and how to realize a quantum computer is one of the difficult problems. However, superconducting circuit is a good system for solving the physics of quantum computers, as it has a solid development history and a perfect fit with quantum computers. In this paper, the development history of the superconducting quantum computer will be reviewed. In addition, the Josephson junction is the basis of superconducting quantum computation, based on which as well as in combination with DiVincenzo’s five requirements, superconducting quantum computers have a great potential. For the main part, the advantages and disadvantages of superconducting a quantum computer are analyzed. Some suggestions are also given and the future of superconducting computer is predicted. In conclusion, the superconducting system is found to be a suitable system for quantum computers.

Superconducting materials have emerged as one of the most promising technologies for building quantum computers. These materials, characterized by their ability to conduct electricity without resistance at low temperatures, enable the creation of qubits, the fundamental units of quantum computation. This article explores the role of superconducting materials in quantum computing, focusing on their properties, applications in quantum systems, and the challenges faced in scaling quantum computers. We discuss the mechanisms behind superconductivity, the engineering advancements in superconducting qubits, and the future potential of this technology in the context of computational efficiency and scalability.
