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…

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…
