High-precision pulse calibration of tunable couplers for high-fidelity two-qubit gates in superconducting quantum processors
Tian-Ming Li, Jia-Chi Zhang, Bing-Jie Chen +23
For superconducting quantum processors, stable high-fidelity two-qubit operations depend on precise flux control of the tunable coupler. However, the pulse distortion poses a signi…

Exploring Hilbert-Space Fragmentation on a Superconducting Processor
Yong-Yi Wang, Yun-Hao Shi, Zheng-Hang Sun +22
Isolated interacting quantum systems generally thermalize, yet there are several examples for the breakdown of ergodicity, such as many-body localization and quantum scars. Recentl…
