Reversely engineered coupling strength gc(t) (continuous line) and g(t) (dotted) as a function of the dimensionless time t/tf for a the GHZ for photonic systems, blue, orange and green data corresponds to the pulse considering α(tf) = 1, 3, 5, respectively. Whereas b stands for the GHZ in qubits. The numerical simulations are preformed with the following system parameters a ω/2π = 6.6 GHz, g/2π = 21 MHz, and b Ω/2π = 10 GHz, ω/2π = 1 GHz, and g/2π = 144 MHz.
