High-contrast ZZ interaction using multi-type superconducting qubits

  title={High-contrast ZZ interaction using multi-type superconducting qubits},
  author={Peng Zhao and P. Xu and D. Lan and X. Tan and Haifeng Yu and Yang Yu},
For building a scalable quantum processor with superconducting qubits, the ZZ interaction is of great concert because of relevant for implementing two-qubit gates, and the close contact between gate infidelity and its residual. Two-qubit gates with fidelity beyond fault-tolerant thresholds have been demonstrated using the ZZ interaction. However, as the performance of quantum processor improves, the residual static-ZZ can also become a performance-limiting factor for quantum gate operations and… Expand
