Superconducting Circuits for Quantum Computing

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.
