0.9.0

We are very excited to share a new toolset added for modeling and manipulating the dynamics of physical systems. The new API allows to define and execute a time evolution under arbitrary operators. For more information, we refer to our docs.
The 0.9.0 release furthermore includes a range of contribution to add new backends to CUDA-Q, including backends from Anyon Technologies, Ferimioniq, and QuEra Computing, as well as updates to existing backends from ORCA and OQC.
A more extensive list of the most important changes, as usual, is given below. We hope you enjoy the new features - also check out our new notebooks and examples to dive into CUDA-Q.

Full Changelog: 0.4.0...0.4.1
Release created by workflow 6408359768.

0.4.0

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.
