PROFILE

Mathieu Gras

Over five months, contributed to ColibrITD-SAS/mpqp by developing and refining core quantum computing features, focusing on circuit optimization, QAOA enhancements, and robust gate handling. Leveraged Python, NumPy, and Qiskit to implement universal unitary decomposition, custom controlled gates, and multi-observable measurement orchestration across cloud backends. Improved reliability through rigorous bug fixing, type hinting, and test-driven development, while enhancing maintainability with code refactoring and comprehensive documentation. Strengthened integration with Cirq and Braket, enabling cross-platform compatibility and accurate observable computation. The work emphasized type safety, error handling, and extensibility, supporting both research and production use cases in quantum algorithm development.
