Purcell-Engineered Hybrid Coupler for Leakage-Suppressed Robust CZ Gates
Hui Wang, Feng Bao, Yan-Jun Zhao +1
We propose a Purcell-engineered notch-filter hybrid coupler for superconducting controlled- (CZ) gates that combines coherent interaction engineering with leakage-selective diss…

On-chip Frequency divider in superconducting quantum circuit
Hui Wang, Chih-Yao Shih, Ching-Yeh Chen +3
Based on the physical process of two-atom simultaneous excitation by single photon, we proposed a frequency dividing scheme in superconducting quantum circuit. The frequency divisi…

Controllable non-Hermitian qubit-qubit Coupling in Superconducting quantum Circuit
Hui Wang, Yan-Jun Zhao, Xun-Wei Xu
We propose a theoretical scheme to realize the controllable non-Hermitian qubit-qubit coupling by adding a high-loss resonator in tunable coupling superconducting quantum circuit.…
