Fluxonium: From a Quantum Phase Transition to a Qubit
The quest for a quantum phase transition in a chain of Josephson junctions has led serendipitously to the invention of a new type of superconducting qubit, which became known as fluxonium. The technology built around it, combined with theoretical efforts, has enabled progress in resolving two puzzles in the physics of superconductors that have persisted for decades.
