A simpler version of the IBM quantum composer (with a user interface), using object oriented c++. The libraries that are mostly used are boost and SFML (for the user interface).
Download all the directories. Keeping up the same structure. Place yourself in the "fichiers_cpp" directory. Open a terminal. Write " make ordi" on the terminal.
Drag and drop the quantum gates on the circuit's line that corresponds to the quibit. Just like the IBM quantum composer. Right click on a quantum gate on circuit line to delete it. Push on the "plus" button to add a quibit. Push on the "minus" button to remove a quibit.
Have fun building your own quantum circuits.
