FYI this will break some cross-references for the migration guides. That's fine because the migration guides are ported already to https://docs.quantum-computing.ibm.com/api/migration-guides and we're planning to switch the qisk.it short links this week to them. The IBM docs will update their links to use the 0.44 version of the API docs

FYI: A PR is updating backend_utils for Aer 0.13 compatibility and is designated to be backported #11172 so I imagine we will want that to merge before the module gets deleted by this PR |

Thanks for doing all this, Elena. It looks like we're on the verge of being ready to go, with overzealous type hints in Aer 0.13 being the only thing that prevents Neko from passing and this from merging.
With Qiskit/qiskit-aer#1996 now merged, we're just waiting on the 0.13.1 patch release of Aer, which at the time of writing, looks just about ready to go: Qiskit/qiskit-aer#1983.

With the removal of algorithms and opflow in Qiskit#11324, Qiskit#11111, and Qiskit#11086 several optional test dependencies are no longer used in the code base. This commit removes them from requirements-optional.txt as several have compatibility issues with Python 3.12 and are causing failures in the nightly builds. Since they're no longer used we shouldn't bother installing them anymore.
