During February 2026, Thomas Soukup focused on improving the correctness and maintainability of diagonal operator arithmetic in the awslabs/palace repository. He addressed a critical bug in complex diagonal operator multiplication, where the imaginary part was previously computed incorrectly, by updating the relevant C++ algorithms to ensure accurate handling of real and imaginary components. Alongside the code fix, he updated the Markdown documentation and changelog to maintain traceability and support future audits. His work leveraged skills in C++ development, algorithm optimization, and linear algebra, restoring numerical accuracy for downstream simulations and enhancing the reliability and maintainability of the codebase.
