Topological Materials for Quantum Computing

Executive Summary

This project will use emerging topological materials to enable new generations of microwave devices that will improve the control and readout of quantum computing hardware. By improving noise protection for quantum states and reducing component size, technologies based on recently discovered topological materials could significantly advance quantum computer development for national security applications.
