Repository: NVIDIA/cudaqx

Tag: 0.3.0

Published: 2025-05-14T14:28:17Z

Prerelease: no

Release notes: The CUDA-QX 0.3.0 release includes updates for CUDA-Q breaking changes (spin ops) and notable performance improvements to our nv-qldpc-decoder. Some of these improvements reduce our average OSD-0 processing by >6X, so try it out!

For details on the breaking changes, see the descriptions in in PRs below along with the associated CUDA-Q PRs:

• https://github.com/NVIDIA/cuda-quantum/pull/2710
• https://github.com/NVIDIA/cuda-quantum/pull/2817

Please check out the docs and examples for how to get started using the CUDA-QX libraries!
