Over thirteen months, Manuel Losada engineered core quantum computing infrastructure in the CESGA-Quantum-Spain/cunqa repository, focusing on scalable circuit execution, robust backend integration, and advanced noise modeling. He developed distributed QPU management and parallelized VQE workflows, leveraging Python, C++, and Qiskit to enable high-performance simulations and reliable experiment orchestration. His work included backend-agnostic circuit transpilation, JSON-driven configuration, and dynamic noise model support, addressing reproducibility and experiment fidelity. Losada also overhauled documentation and API usability, improved error handling, and maintained repository hygiene. The depth of his contributions established a maintainable, extensible foundation for quantum simulation and research workflows.

Jan 1, 2025January 2025 monthly summary for CESGA-Quantum-Spain/cunqa. Delivered core enhancements to the Quantum Circuit Execution API and simulation backbone, focusing on usability, reliability, and business value. End-to-end execution support for a 15-qubit, 10-layer circuit was introduced in the api-dev branch with robust configuration loading and clearer usage examples. The simulation workflow was enhanced with improved logging, JSON-based circuit construction and transpilation, and refactored execution/data handling to support qjob execution and result handling. A dedicated effort to reliability finished with a refactor of the Result class to correctly parse counts and metadata, plus basic logging and notebook updates for reliable outcome interpretation. Collectively, these changes reduce debugging time, increase end-user confidence, and lay the groundwork for production readiness. Technologies demonstrated include API design and configuration loading, JSON-based circuit representation, transpilation, structured logging, data parsing, and notebook-driven observability.
