During June 2025, Riley contributed to the sandialabs/pyGSTi repository by addressing a critical bug in the idle gate dimension calculation within optools.py. Riley applied expertise in Python, linear algebra, and numerical computing to ensure the idle gate is now constructed with the correct dimension based on the system’s dimension squared, rather than a potentially reduced value caused by leakage. This fix prevents mis-sizing issues that could compromise simulation fidelity, resulting in more accurate gate simulations and improved calibration workflows. Riley’s focused engineering work enhanced the reliability of downstream processes, demonstrating depth in both problem analysis and technical implementation.
