We want to improve our test coverage in the short term and require unit tests in the long term. Here are some things, that still need to be tested: -...

Branch for refactoring the low-level QNN implementation to make it more modular: - [x] Create QNN Base Class derived from the current low-level QNN implementation (@David-Kreplin) - [x] Adjust existing...

The caching and restarts are only working for primitives so far.

At the moment, logging of the optimization works only at the optimizer level. Since we added now variance regularization and shot adjustment, I would suggest to implement a logging feature...
