Millikelvin digital-to-analog converter for superconducting quantum processors
Ruizi Hu, Zongyuan Li, Zhancheng Yao +19
Scaling superconducting quantum processors is increasingly constrained by the wiring, heat load, and calibration overhead associated with delivering high-resolution analog signals…
Scalable Fluxonium Quantum Processors via Tunable-Coupler Architecture
Ze Zhan, Zishuo Li, Fei Wang +24
Superconducting quantum processors have largely converged on transmon-based architectures, while alternative qubit modalities with intrinsic error protection have lacked a demonstr…
Mapping Topology-Localization Phase Diagram with Quasiperiodic Disorder Using a Programmable Superconducting Simulator
Xuegang Li, Huikai Xu, Junhua Wang +23
We explore topology-localization phase diagram by simulating one-dimensional Su-Schrieffer-Heeger (SSH) model with quasiperiodic disorder using a programmable superconducting simul…
Vacuum-gap transmon qubits realized using flip-chip technology
Xuegang Li, Yingshan Zhang, Chuhong Yang +26
Significant progress has been made in building large-scale superconducting quantum processors based on flip-chip technology. In this work, we use the flip-chip technology to realiz…
Transmon qubit with relaxation time exceeding 0.5 milliseconds
Chenlu Wang, Xuegang Li, Huikai Xu +25
By using the dry etching process of tantalum (Ta) film, we had obtained transmon qubit with the best lifetime (T1) 503 us, suggesting that the dry etching process can be adopted in…
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…
