"high-precision two-qubit gates: fSim and CZ... bring qubits into resonance with each other, parametric modulation of flow of one qubit of the system used... accuracy of two-qubit operations above 99.22%, but also to suppress the residual ZZ interaction between the qubits, which allowed to perform parallel single-qubit operations with an accuracy of 99.97%... subgigahertz electronics in qubit control lines reduces complexity quantum processor control"
