Basically something like the docstring used here: https://github.com/quantumlib/Cirq/blob/d58423a3f06dd0a40fd8acfdd006d9a876274a7c/cirq/circuits/qasm_output.py#L86

**What is the urgency from your perspective for this issue? Is it blocking impo

To get this codebase up to standard, we need to add type hints. At the very least, perhaps we should start insisting that all new code has type hints added, but moreover we need to add typing to the code that currently exists.

This is a pretty large project, but luckily it can be done incrementally - I believe at this point it's a stretch goal for v1, if anyone wants to help it would be much ap

It would be nice to allow users to set a custom value for the tensorflow dtype if they are really pushing their simulations (and aware of the memory tradeoffs). This would be a very straightforward feature to add, most likely by adjusting backend_options to accept a dtype argument or something similar

Now, there's no unit test.

Whenever a slide has minted code, like so:

\begin{frame}[fragile]{Example minted}
	\begin{minted}{python}
		from qiskit_aqua import run_algorithm

		print(run_algorithm(params)['result'])
	\end{minted}
\end{frame}

One is unable to add the \pagenumber before \end{frame} as it gets left aligned instead of right aligned:

RDMs returned from pyscf are spin summed. Use https://sunqm.github.io/pyscf/_modules/pyscf/fci/direct_spin1.html#FCISolver.make_rdm12s

to return non-spin summed versions. Recombine spin-separated RDMs like run_psi4 to get spin-orbital rdms before returning to OpenFermion.
