The 0.6.0 release contains improved support for various HPC scenarios. We have added a plugin infrastructure for connecting CUDA Quantum with an existing MPI installation, and we've added a new platform target that distributes workloads across multiple virtual QPUs, each simulated by one or more GPUs.

Starting with 0.6.0, we are now also distributing pre-built binaries for using CUDA Quantum with C++. The binaries are built against the GNU C library version 2.28. We've added a detailed Building from Source guide to build these binaries for older glibc versions.

CUDA Quantum is now available on PyPI!
For the initial PyPI release, the NVIDIA multi-gpu and tensornet backends are not yet included. Check out our Docker images on NGC to obtain the fully featured version, or build it from source using the release assets.
With 0.4.0 we have added support for quantum kernel execution on Quantinuum and IonQ backends. For more information, see our docs.
As always, we welcome questions and feedback in the form of issues and discussions on this repository.
