Worked on the sandialabs/pyGSTi repository to deliver Qiskit 2.1.0 compatibility updates across core components, focusing on seamless integration with the latest quantum computing APIs. Addressed changes in the IBMQExperiment class to ensure reliable retrieval of circuit batch results and consistent sampler initialization using session mode for all jobs. Leveraged Python for API integration and dependency management, updating the pyGSTi library to align with Qiskit 2.1.0 and its runtime requirements. This work enabled smoother upgrades for users and improved runtime reliability, reflecting a targeted approach to library integration and maintenance within the quantum computing ecosystem.
