GST results. SPAM-free Pauli transfer matrices, process infidelities, diamond distances, stochastic Pauli errors, and coherent Pauli errors for gates on resonant- and detuned-KCQs. (A) resonant-KCQ $X(\pi /2)$ gate with 367-ns gate time. (B) resonant-KCQ $Z(\pi /2)$ gate with 70-ns gate time. (C) detuned-KCQ $X(\pi /2)$ gate with 418-ns gate time. (D) detuned-KCQ $Z(\pi /2)$ gate with 70-ns gate time. The uncertainty represents the SD of the model fitting, and each circuit in GST is repeated by 1,024 shots.
