Branch-resolved Pauli-block spectroscopy of residual conditional phase in two-qubit gates
Xudan Chai, Yanwu Gu, Huiqi Xue +2
The paper introduces a branch‑resolved Pauli‑block spectroscopy technique to directly estimate the signed residual conditional phase (ZZ‑type rotation) in two‑qubit controlled‑phas…
Möbius-Guided Diagonal-Gate Compilation with Native Multiqubit Controlled-Phase Gates on Neutral-Atom Processors
Hairuo Huang, Yanwu Gu, Chen Huang +4
Diagonal gates are ubiquitous primitives in quantum algorithms, from phase oracles, hypergraph-state preparation, and multi-control logic to Hamiltonian simulation of spin models a…
Topology-Aware Block Coordinate Descent for Qubit Frequency Allocation of Superconducting Quantum Processors
Zheng Zhao, Weifeng Zhuang, Yanwu Gu +3
Pre-execution calibration is a major bottleneck for operating superconducting quantum processors, and qubit frequency allocation is especially challenging due to crosstalk-coupled…
Mitigating Errors in Analog Quantum Simulation by Hamiltonian Reshaping or Hamiltonian Rescaling
Rui-Cheng Guo, Yanwu Gu, Dong E. Liu
Simulating quantum many-body systems is crucial for advancing physics but poses substantial challenges for classical computers. Quantum simulations overcome these limitations, with…
