This item is a response to a research question in Quantum Technologies
Q. What is robust control in quantum technology?

Abstract

This dataset contains the code and data for investigation of the differential sensitivity of the gate infidelity to parametric (structured) uncertainty. The provided controllers are piecewise constant, dynamic controls optimized to maximize gate fidelity across nine problems of varying system complexity and control paradigms. The analysis code computes bounds on the differential sensitivity and statistically analyses the relationship between the infidelity and sensitivity bounds. The analysis code also provides plots to aid in visualization of the statical data.

Description
The files in this directory contain all the MATLAB code and data necessary to generate the results and figures. Running the calc_all_script.m routine establishes the necessary folder hierarchy, extracts the controller data from the /controllers directory, computes sensitivity data, and saves the results in the /results directory. The plot_all_script.m routine then uses these results to generate the visualization products and saves them in the /figures directory. See the README for further details.
