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.
