Henri de Boutray developed and maintained core quantum computing workflows for the ColibrITD-SAS/mpqp repository, focusing on circuit execution, measurement handling, and QAOA/QUBO tooling. He refactored backend pipelines for clearer transpilation and cross-platform reliability, improved local storage and environment management, and enhanced noise model integration. Using Python and JavaScript, Henri implemented robust API integrations, database management, and automated testing, while strengthening documentation and code readability. His work addressed complex issues such as symbolic gate export, custom gate flexibility, and Docker cross-OS compatibility, resulting in a more maintainable, reliable, and developer-friendly codebase that supports advanced quantum computing scenarios.

July 2025: Performance-focused month for ColibrITD-SAS/mpqp. Focused on delivering usable QAOA/QUBO tooling, strengthening noise-model reliability, and improving maintainability. Key features shipped include QAOA/QUBO API and usability improvements (docs, type hints, notebook updates) with a default optimizer to simplify onboarding and usage; and noise model enhancements (hashable NoiseModel, refactored noise application to Cirq for reliability and performance). Major bugs fixed include the CustomGate flexibility bug fix removing the restrictive security check to allow non-contiguous and non-ordered target qubits (with new tests), and a missing import in theoretical_simulation that caused a runtime error. Code quality and documentation improvements delivered across core classes and tests, improving readability and maintainability.
