PROFILE
Alec Edgington
Alec Edgington contributed to the CQCL/tket repository by delivering targeted improvements in quantum circuit transpilation and build infrastructure. He implemented a TK2-based rebase transformation, replacing CX as the intermediate gate to enhance transpilation efficiency and consistency, and managed related dependency upgrades and versioning. Alec also established test-driven diagnostics for conditional gate synthesis issues, adding regression coverage for gate-angle restrictions. In addition, he upgraded core dependencies such as Boost and the TKET library, stabilized CI/CD workflows by refining GitHub Actions configurations, and explored multi-threading in test builds using CMake and C++. His work demonstrated depth in build systems and quantum compiler optimization.

5 Commits • 2 Features
Jan 1, 2026January 2026 (CQCL/tket): Delivered key feature upgrades, stabilized CI, and advanced test configuration while ensuring stability. Implemented dependency upgrades for improved compatibility and performance, stabilized CI/CD workflow naming to ensure reliable builds, and explored multi-threading in tests with a temporary revert to preserve stability. This period established a stronger baseline for future threading work and performance improvements.

Dec 1, 2024December 2024 monthly summary (CQCL/tket) Key features delivered - TK2-based rebase improvement: Rebase_TK now uses TK2 as the intermediate gate instead of CX, improving transpilation efficiency and consistency. This feature group includes a dependency upgrade to support TK2 and a changelog entry signaling the improvement. Release is accompanied by a version bump to reflect the change. Major bugs fixed - Not yet merged: A failing test was added to reproduce a gate-angle restriction issue in conditional 2-qubit ZZPhase synthesis (SynthesiseTK). Investigation is in progress to diagnose and fix the restriction, with test coverage in place to prevent regression. Overall impact and accomplishments - Improved transpilation performance and consistency by introducing TK2-based rebase, reducing CX-based intermediates and aligning with TK2-enabled optimizations. - Enhanced release hygiene through a version bump and changelog updates, aiding downstream users and CI validation. - Established diagnostic groundwork for gate-angle correctness in SynthesiseTK, setting up faster resolution for conditional ZZPhase synthesis issues. Technologies/skills demonstrated - Gate-level synthesis optimization (TK2 as intermediate gate) - Dependency management and release/version control - Test-driven development (adding failing test for regression coverage) - Documentation and changelog maintenance - CI-friendly changes with clear commits and traceability
