  • 3.Realization of adiabatic and diabatic CZ gates in superconducting qubits coupled with a tunable coupler

    • 关键词:
    • controlled-Z gates; high fidelity gates; tunable coupler

    High fidelity two-qubit gates are fundamental for scaling up the superconducting qubit number. We use two qubits coupled via a frequency-tunable coupler which can adjust the coupling strength, and demonstrate the CZ gate using two different schemes, adiabatic and diabatic methods. The Clifford based randomized benchmarking (RB) method is used to assess and optimize the CZ gate fidelity. The fidelities of adiabatic and diabatic CZ gates are 99.53(8)% and 98.72(2)%, respectively. We also analyze the errors induced by the decoherence. Comparing to 30 ns duration time of adiabatic CZ gate, the duration time of diabatic CZ gate is 19 ns, revealing lower incoherence error rate r(incoherent,int)' = 0.0197(5) compared to r(incoherent,int) = 0.0223 (3).
