from this paper in the IBM Quantum Composer. However, this circuit isn't enough understandable for me to do so.
I have tried to recreate the above circuit in the composer as follows
I've tried to recreate the following two gates for the MEF
as U(0,0,0,0) and nG2 where nG2 is
Obviously, I can be sure that my approach is wrong as I even don't know how to make one measurement affect the next one (recreate the lines conecting measurements with $R_{\pi/2}$ and $R_{\pi/4}$) and how to implement the MEF gates.
How should I recreate the given circuit in the IBM Quantum Composer to obtain the factors of $N=15$ ?
