The typical way to implement the Rydberg excitation – is a two-photon transition via the intermediate states. While this excitation scheme is necessary for coherent qubit control, it also introduces additional error mechanisms, such as spontaneous decay from the intermediate state, which can affect gate fidelity. Another category of primary error sources is the finite Rydberg lifetime, as the atoms excited to Rydberg states eventually decay due to spontaneous emission with decay rate γr , further contributing to incoherent losses. The optimization objective is to find the optimal laser pulses that maximize the fidelity of the CZ gate while minimizing the inelastic losses, Rydberg blockade leakage pulse energy and its duration.
