0.5.0

With 0.5.0 we have added support for quantum kernel execution on OQC and IQM backends. For more information, see our docs. CUDA Quantum now allows to executing adaptive quantum kernels on quantum hardware backends that support it. The 0.5.0 release furthermore improves the tensor network simulation tools and adds a matrix product state simulator.

Additionally, we are now publishing images for experimental features, which currently includes improved Python language support. Please take a look at our installation guide for more information about how to obtain them.
