Simultaneous determination of multiple low-lying energy levels on a superconducting quantum processor
Huili Zhang, Yibin Guo, Guanglei Xu +4
Determining the ground and low-lying excited states is critical in numerous scenarios. Recent work has proposed the ancilla-entangled variational quantum eigensolver (AEVQE) that u…
Observing Quantum Correlation Dynamics in Tunable Superconducting Bose-Hubbard Simulators
Z. T. Wang, Si-Yun Zhou, Yun-Hao Shi +18
The dynamics of quantum correlations are central to understanding many physical properties of quantum systems. Here we experimentally study the correlation dynamics via two-particl…
Simultaneous determination of multiple low-energy eigenstates of many-body systems on a superconducting quantum processor
Huili Zhang, Yibin Guo, Guanglei Xu +4
The determination of the ground and low-lying excited states is critical in many studies of quantum chemistry and condensed-matter physics. Recent theoretical work proposes a varia…
Quafu-Qcover: Explore Combinatorial Optimization Problems on Cloud-based Quantum Computers
BAQIS Quafu Group
We present Quafu-Qcover, an open-source cloud-based software package designed for combinatorial optimization problems that support both quantum simulators and hardware backends. Qu…
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…
