Refactor `ooVQE`

Open mrossinek opened this issue 3 years ago • 3 comments

What is the expected enhancement?

The ooVQE did not make it into the last release because it needs to undergo a major refactoring to fit into the framework of Qiskit Nature. The most up-to-date (but WIP) version of ooVQE can be found here

I am replicating a (non-exhaustive) TODO list from that file below:

  • [ ] removal of molecular_problem from __init__ (this will only be given to solver())
  • [ ] actual use of MolecularProblem.second_q_ops() rather than hard-coded build_fermionic_op
  • [ ] unification with BaseProblem.solve()
  • [ ] general refactorings of flow
  • [ ] fix freeze-core support based on FreezeCoreTransformer
  • [ ] fix dependence on num_parameters handling within Terra's VQE and Optimizer

I think that this could be a good first issue for me, but it might take more than one sprint with my current bandwidth. Would you like me to work on it?

@ElePT that would be great. I will split in multiple issues and assign them to you. Thank you very much!

Changing this issue into an epic for better tracking, as it will be divided into 2.
