Superconductivity
摘要
In this chapter, the basics of superconductivity are covered, along with technological spin-offs, the Josephson function, and the SQUID. Superconducting devices are interesting in their own right, not least because they are an example of a system that can have a coherent wavefunction on a macroscopic size scale. But superconducting materials and devices are also promising systems for implementing quantum computation protocols.
