During four months contributing to the CESGA-Quantum-Spain/cunqa repository, Daniel Expósito focused on enhancing distributed quantum simulation infrastructure and modernizing developer documentation. He integrated the CunqaCircuit infrastructure into CunqaSimulator, improving circuit validation, QPU allocation, and distributed execution reliability. Daniel standardized circuit data structures and register mapping across backends, implemented safeguards for distributed workflows, and overhauled documentation using Sphinx and reStructuredText to streamline onboarding and API discoverability. His work, primarily in Python and C++, included dependency management and recursive module documentation, resulting in a more maintainable codebase and improved developer experience for both new contributors and cross-team collaborations.

July 2025 – Key features delivered include documentation clarification for the Result API (Result class docstring) and alignment with an updated cunqasimulator subproject dependency. Major bugs fixed: none this month. Overall impact: improved API clarity, reduced onboarding time for new developers, and more stable cross-project integrations with cunqasimulator. Technologies/skills demonstrated: Python docstring standards, dependency management, and Git-based change traceability (commit 9c9546e8154c7fd02ea66594424bd316b86c427d).

Month: 2025-06 — Cunqa Documentation Modernization and API docs template delivered for CESGA-Quantum-Spain/cunqa. The work focused on consolidating and modernizing package documentation to improve API discoverability and developer onboarding, including a complete restructuring of docs with cunqa.rst, an autosummary-based approach for recursive module docs, an auto-toctree setup for the Cunqa package, and the introduction of module_template_2.rst for clearer module API presentation. This enhances maintainability, reduces onboarding time, and supports faster engineering cycles for API usage.
