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…
On-demand shaped photon emission based on a parametrically modulated qubit
Xiang Li, Sheng-Yong Li, Si-Lu Zhao +13
In the circuit quantum electrodynamics architectures, to realize a long-range quantum network mediated by flying photon, it is necessary to shape the temporal profile of emitted ph…
Tunable coupling of a quantum phononic resonator to a transmon qubit with flip-chip architecture
Xinhui Ruan, Li Li, Guihan Liang +16
A hybrid system with tunable coupling between phonons and qubits shows great potential for advancing quantum information processing. In this work, we demonstrate strong and tunable…
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…
Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor
Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24
Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
