Improving Quantum Gate Fidelity with Universal Differential Equations

Stefanie Guenther | 23-ERD-038

Executive Summary

This project will improve the error rate of logical gates on supercomputing quantum devices by augmenting the quantum dynamical model with a data-driven approach based on universal differential equations. This will enable co-design of quantum hardware and control techniques to provide accurate simulation and optimization of many-body quantum systems.
