Dressed-state relaxation in coupled qubits as a source of two-qubit gate errors
Ruixia Wang, Jiayu Ding, Chenlu Wang +8
Understanding error mechanisms in two-qubit gate operations is essential for building high-fidelity quantum processors. While prior studies predominantly treat dephasing noise as e…
Experimental Realization of Criticality-Enhanced Global Quantum Sensing via Non-Equilibrium Dynamics
Yefei Yu, Ran Liu, Guangming Xue +8
Quantum critical systems offer promising advancements in quantum sensing and metrology, yet face limitations like critical slowing down and a restricted criticality-enhanced region…
Multi-Purpose Architecture for Fast Reset and Protective Readout of Superconducting Qubits
Jiayu Ding, Yulong Li, He Wang +12
The ability to fast reset a qubit state is crucial for quantum information processing. However, to actively reset a qubit requires engineering a pathway to interact with a dissipat…
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…
