a Phase damping, b amplitude damping, and c residual ZZ-coupling between qubits with a two-qubit gate time of tg = 315 ns. The average T2, T1, and frequency of the residual ZZ-coupling for the given device are 82 μs, 64 μs, and 102 kHz respectively. The shaded regions indicate one standard deviation of uncertainty.
