Large superconducting circuits can be analyzed with a new theoretical tool developed by Northwestern University researchers. "Our framework is inspired by methods originally developed for the study of electrons in crystals and allows us to obtain quantitative predictions for circuits that were previously hard or impossible to access," said Northwestern's Daniel Weiss.

Researchers used the tool to extract quantitative information from a protected circuit, and the method complements existing, similarly purposed tools for when they yield suboptimal results. This work dovetails with the missions of the U.S. Department of Energy's Superconducting Quantum Materials and Systems Center and the Co-design Center for Quantum Advantage. Their respective goals are building a superior superconducting, technologies-based quantum computer, and constructing basic tools for assembling scalable, distributed, and fault-tolerant quantum computers.
