Worked on CQCL/qnexus and CQCL/pytket-quantinuum repositories, focusing on backend development and CI/CD stability. Improved build reliability in qnexus by pinning GitHub Actions runners to Ubuntu 24.04, ensuring consistent environments and reducing flaky builds. Enhanced the QuantinuumBackend in pytket-quantinuum by introducing a Clifford circuit predicate, which enforced simulator constraints and improved simulation integrity. Delivered cost-control features and job timing visibility by adding a max_cost parameter and start-date parsing, enabling users to manage hardware spend and monitor job execution. Utilized Python, YAML, and cloud services, emphasizing robust API integration, automated testing, and clear changelog documentation throughout the work.
Summary for May 2025 (CQCL/pytket-quantinuum): Focused on delivering cost-control and visibility enhancements for the Quantinuum backend to improve hardware spend predictability and job timing insight. No major bugs fixed this month. The work delivers business value by enabling cost caps on HQC processing, improving scheduling visibility, and maintaining clear release notes for users. Demonstrated technologies include Python backend enhancements, API parameterization, robust job-status parsing, and changelog maintenance. Overall impact: improved cost predictability for HQC workloads and clearer runtime visibility for users.

February 2025 monthly summary for CQCL/pytket-quantinuum: Delivered improvements to stabilizer simulation reliability by introducing a Clifford circuit predicate in the QuantinuumBackend to ensure the stabilizer simulator processes only Clifford circuits. This prevents errors and maintains simulation integrity. Updated changelog and added tests to validate the new functionality, and to document the behavioral constraints.
