Realisation of adiabatic and diabatic CZ gates in superconducting qubits coupled with a tunable coupler
Huikai Xu, Weiyang Liu, Zhiyuan Li +11
High fidelity two-qubit gates are fundamental for scaling up the superconducting number. We use two qubits coupled via a frequency-tunable coupler which can adjust the coupling str…
Suppression of static ZZ interaction in an all-transmon quantum processor
Peng Zhao, Dong Lan, Peng Xu +5
The superconducting transmon qubit is currently a leading qubit modality for quantum computing, but gate performance in quantum processor with transmons is often insufficient to su…
Characterize noise correlation and enhance coherence via qubit motion
Jiaxiu Han, Zhiyuan Li, Jingning Zhang +11
The identification of spacial noise correlation is of critical importance in developing error-corrected quantum devices, but it has barely been studied so far. In this work, we uti…
Simultaneously exciting two atoms with photon-mediated Raman interaction
Peng Zhao, Xinsheng Tan, Haifeng Yu +2
We propose an approach to simultaneously excite two atoms by using cavity-assisted Raman process in combination with cavity photon-mediated interaction. The system consists of a tw…
Switchable next-nearest-neighbor coupling for controlled two-qubit operations
Peng Zhao, Peng Xu, Dong Lan +3
In a superconducting quantum processor with nearest neighbor coupling, the dispersive interaction between adjacent qubits can result in an effective next-nearest-neighbor coupling…
High-contrast ZZ interaction using superconducting qubits with opposite-sign anharmonicity
Peng Zhao, Peng Xu, Dong Lan +4
For building a scalable quantum processor with superconducting qubits, ZZ interaction is of great concern because its residual has a crucial impact to two-qubit gate fidelity. Two-…
