PROFILE

Mathieug-colibri

Mathieu Gras developed advanced quantum optimization tooling for the ColibrITD-SAS/mpqp repository, focusing on QAOA integration, unitary matrix decomposition, and robust circuit simulation. He implemented features such as universal unitary decomposition, custom controlled gates, and multi-observable Pauli grouping, using Python and libraries like NumPy and Qiskit. His work included algorithm development, backend integration, and extensive code refactoring to improve reliability and maintainability. Mathieu addressed complex bugs in matrix operations and expectation calculations, enhanced documentation, and stabilized the test suite. These contributions enabled more accurate quantum experiments and streamlined research workflows, reflecting a deep understanding of both software engineering and quantum computing.
