GHZ-like state preparation assisted by DDQCL. Left (right) panel shows a recipe obtained by a human expert assisted by DDQCL for the even (odd) cat state preparation. Rx stands for the single qubit rotation about the x axis. GMS stands for a global Mølmer-Sørensen gate46 acting on all the N = 2n (N = 2n + 1) qubits and is equivalent to the application of local XX gates to all N(N − 1)/2 pairs of qubits. All parameters attained values very close to \(\frac{\pi }{2}\). The human expert rounded the parameters to some precision and found these patterns
