David Expósito developed core distributed quantum computing features for the CESGA-Quantum-Spain/cunqa repository, focusing on scalable execution and robust configuration. He implemented distributed Quantum Phase Estimation, unified simulation result formats across AER, Munich, and CunQA backends, and enabled dynamic simulator selection to support diverse quantum workflows. Using Python and C++, David standardized backend data handling, improved error logging, and enhanced documentation reliability through Sphinx configuration. His work addressed cross-simulator interoperability, streamlined onboarding, and reduced integration friction. By refining input validation, output normalization, and distributed execution, David delivered maintainable, extensible solutions that improved reliability and accelerated scientific analysis for quantum experiments.

Jun 1, 2025June 2025 monthly summary for CESGA-Quantum-Spain/cunqa: Key features delivered - Unified Simulation Results and Backend Consistency: Consolidated circuit ID formatting, distributed run handling, and backend result normalization across simulators. Introduced helpers to convert CUNQA results to a standard format and to reverse bitstrings so AER, Munich, and CUNQA share a consistent output representation. This work standardizes cross-simulator outputs and reduces downstream integration effort. Major bugs fixed - Documentation build stability: Mocked the copy module in Sphinx to prevent documentation build failures when the module is unavailable, ensuring reliable docs generation. Overall impact and accomplishments - Improved cross-simulator interoperability and data integrity by standardizing results and normalization across the core CunQA workflow, enabling faster debugging and more reliable comparisons between AER, Munich, and CunQA outputs. - Enhanced documentation reliability, reducing CI friction and improving developer onboarding with stable docs builds. Technologies/skills demonstrated - C++ implementation and refactoring to standardize result handling - Cross-simulator data normalization and bitstring handling - Python/Sphinx configuration and testability improvements (mocking modules for stable builds) - Distributed run handling and output representation consistency

May 1, 2025May 2025 (Month: 2025-05) - Focused on delivering a distributed QPE capability in Cunqa (CESGA-Quantum-Spain/cunqa) and strengthening configuration validation and error handling. Key outcomes include a distributed QPE framework with environment setup, distributed circuits, QPU allocation, and execution across multiple resources, plus enhanced logging, parameter handling, and output tracking for distributed QPE. Added simulator validation to prevent misconfigurations and refined error logging for memory/time formats. Fixed critical issues in the distributed path (notably ZMQ communications) and improved error messaging for unsupported distributed gates, improving reliability and troubleshooting. These workstreams enable scalable quantum experimentation and reduce onboarding friction for new users.
