<!-- Release notes generated using configuration in .github/release.yml at e0fb95f99b955acca530fcedeb3acd109d9d0183 -->

The 0.6.0 release contains improved support for various HPC scenarios. We have added a [plugin infrastructure](https://nvidia.github.io/cuda-quantum/0.6.0/install.html#distributed-computing-with-mpi) for connecting CUDA Quantum with an existing MPI installation, and we've added a [new platform target](https://nvidia.github.io/cuda-quantum/0.6.0/using/cudaq/platform.html#remote-mqpu-platform) 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](https://nvidia.github.io/cuda-quantum/0.6.0/install.html#pre-built-binaries) for using CUDA Quantum with C++. The binaries are built against the [GNU C library](https://www.gnu.org/software/libc/) version 2.28. We've added a detailed [Building from Source](https://nvidia.github.io/cuda-quantum/0.6.0/data_center_install.html) guide to build these binaries for older `glibc` versions.

Release created by workflow [6408359768](https://github.com/NVIDIA/cuda-quantum/actions/runs/6408359768).

CUDA Quantum is now available [on PyPI](https://pypi.org/project/cuda-quantum/)!
For the initial PyPI release, the NVIDIA multi-gpu and tensornet backends are not yet included. Check out our Docker images [on NGC](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/cuda-quantum) 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](https://nvidia.github.io/cuda-quantum/latest/using/hardware.html).
As always, we welcome questions and feedback in the form of [issues](https://github.com/NVIDIA/cuda-quantum/issues/new/choose) and [discussions](https://github.com/NVIDIA/cuda-quantum/discussions) on this repository.
