Assigning myself to specify what is needed to solve this issue. I had just created this issue quickly to flag what was mentioned in https://github.com/unitaryfund/mitiq/pull/2113#issuecomment-1863625596, but I do recognize I need to follow up here.

*If someone wants to investigate and fill in the issue description before I get a chance to do it, more than welcome! Otherwise I'll pick it up.
