Quantum crosstalk analysis for simultaneous gate operations on superconducting qubits
Peng Zhao, Kehuan Linghu, Zhiyuan Li +5
Maintaining or even improving gate performance with growing numbers of parallel controlled qubits is a vital requirement for fault-tolerant quantum computing. For superconducting q…
Realizing discrete time crystal in an one-dimensional superconducting qubit chain
Huikai Xu, Jingning Zhang, Jiaxiu Han +5
Floquet engineering, i.e. driving the system with periodic Hamiltonians, not only provides great flexibility in analog quantum simulation, but also supports phase structures of gre…
Probing Operator Spreading via Floquet Engineering in a Superconducting Circuit
S. K. Zhao, Zi-Yong Ge, Zhongcheng Xiang +16
Operator spreading, often characterized by out-of-time-order correlators (OTOCs), is one of the central concepts in quantum many-body physics. However, measuring OTOCs is experimen…
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…
