Perturbation impact of spectators on a cross-resonance gate in a tunable coupling superconducting circuit
T. -Q. Cai, X. -Y. Han, Y. -K. Wu +7
Cross-resonance (CR) gate has emerged as a promising scheme for fault-tolerant quantum computation with fixed-frequency qubits. We experimentally implement entangling CR gate by us…

Error analysis in suppression of unwanted qubit interactions for a parametric gate in a tunable superconducting circuit
X. Y. Han, T. Q. Cai, X. G. Li +7
We experimentally demonstrate a parametric iSWAP gate in a superconducting circuit based on a tunable coupler for achieving a continuous tunability to eliminate unwanted qubit inte…

Tunable coupler for realizing a controlled-phase gate with dynamically decoupled regime in a superconducting circuit
X. Li, T. Cai, H. Yan +13
Controllable interaction between superconducting qubits is desirable for large-scale quantum computation and simulation. Here, based on a theoretical proposal by Yan et al. [Phys.…
