Jul 1, 2025Concise monthly summary for NVIDIA/cudaqx (July 2025). The CUDA-Q ecosystem advanced with a Generative Quantum Eigensolver (GQE) integration in CUDA-Q Solvers, improved runtime resilience through robust decoder dependency error handling, and preparatory work for Python 3.13 compatibility across build, validation, and runtime environments. Additionally, documentation improvements clarified CUDA-Q QEC library usage and tensor network decoder guidance, and maintenance work upgraded core dependencies with licensing alignment. These efforts collectively improve functionality, stability, onboarding, and compliance, while strengthening CI/CD reliability and future-proofing for broader ecosystem support.

Jun 1, 2025June 2025 monthly summary for NVIDIA/cudaqx focusing on delivering a flexible decoder API extension and strengthening internal data handling to support optional outputs. Key work delivered includes introducing an opt_results field in decoder_result to enable decoders to return optional outputs via a heterogeneous map, accompanied by breaking changes to C++/Python interfaces. Internal improvements to heterogeneous_map were implemented to support flexible storage of outputs. Documentation and examples were updated to reflect the new API usage. No customer-reported bugs fixed this month; however, internal stability and maintainability improvements reduce potential copy-related issues.
