Feedback buttons in Tutorials (and similar places)

### What is the expected behavior? It would be great to get user feedback directly in places where they interact with our code. One option could be to add a...

Add explanantion on Opflow's ``StateFn(H, is_measurement=True) @ state``

1

### Summary Add a paragraph explananing Opflow's ``StateFn(H, is_measurement=True) @ state`` notation. ### Details and comments Also exchanges `StateFn(H).adjoint()` with `StateFn(H, is_measurement=True)` as the latter doesn't take the complex conjugate...

### What is the expected behavior? For statevector simulations we can use faster classical evaluation schemes for the gradients, as proposed in https://arxiv.org/abs/2009.02823 and https://arxiv.org/abs/2011.02991. These methods are significantly faster...

Nuclear repulsion energy is tough to find!

4

### What is the expected enhancement? It's pretty difficult to find the nuclear repulsion energy (and probably some other interesting properties) if one doesn't already know where to look: ```python...

Runtime programs should store the history w/o requiring active user-server link

3

### What should we add? To obtain the history of a VQE run right now, we pass a callback into the `VQEClient` that forwards information from the energy evaluation on...

### What should we add? Support custom mixers and initial states in the ``QAOAClient``. This is also required for #358 since the warm starting requires setting both these attributes. To...

### What should we add? The ``WarmStartQAOAOptimizer`` currently only allows a ``QAOA`` object as input for the QAOA algorithm. It would be great to extend this to also support the...

Allow loading a `MinimumEigensolverResult` directly into the `MinimumEigenOptimizer`

4

### What should we add? The `MinimumEigenOptimizer` internally calls a minimum eigensolver and then postprocesses the obtained `MinimumEigensolverResult` in the context of the quadratic program that we try to solve....

Sampler-based VQE for diagonal operators, plus QAOA

5

### Summary Add a VQE variant based on the sampler primitive, which only allows for optimization of diagonal ("classical") Hamiltonians. Adds QAOA based on the above. closes #8472 ### Details...

Dynamical decoupling with `GenericBackendV2`

1

### Environment - **Qiskit version**: 1.0.0rc1 - **Python version**: 3.11 - **Operating system**: macOS ### What is happening? It seems the single qubit durations in the `GenericBackendV2` are of the...
