Clean up

[andrea-pasquale]

As I was reviewing the code I decided to remove some parts that are currently not used (or so I believe).
The script is working also on this branch.
@marekgluza I noticed that when I try to run things using the first order group commutator the code is crashing with the following error:

ValueError: Cannot add circuits with different kwargs. nqubits is 9 for first circuit and 10 for the second.

Instead when I run with the third order commutator everything seems fine.
