Microwave electrometry with quantum-limited resolutions in a Rydberg atom array
Yao-Wen Zhang, De-Sheng Xiang, Ren Liao +6
Microwave (MW) field sensing is foundational to modern technology, yet its evolution, reliant on classical antennas, is constrained by fundamental physical limits on field, tempora…
Observation of non-Hermitian many-body phase transition in a Rydberg-atom array
Yao-Wen Zhang, Biao Xu, Yijia Zhou +8
Non-Hermitian quantum mechanics with parity-time (PT) symmetry offers a powerful framework for exploring the complex interplay of dissipation and coherent interactions in open quan…
Distributed-HISQ: A Distributed Quantum Control Architecture
Yilun Zhao, Kangding Zhao, Peng Zhou +12
The design of a scalable Quantum Control Architecture (QCA) faces two primary challenges. First, the continuous growth in qubit counts has rendered distributed QCA inevitable, yet…
Quantum State Preparation by Improved MPS Method
Chao Wang, Pengrui Zhou, Xi-Ning Zhuang +4
Efficient encoding of classical information plays a fundamental role in numerous practical quantum algorithms. However, the preparation of an arbitrary amplitude-encoded state has…
Real-time scattering and freeze-out dynamics in Rydberg-atom lattice gauge theory
De-Sheng Xiang, Peng Zhou, Chang Liu +8
Understanding the non-equilibrium dynamics of gauge theories remains a fundamental challenge in high-energy physics. Indeed, most large scale experiments on gauge theories intrinsi…
Tensor-network variational diagonalization of quantum many-body spectra
Peng-Fei Zhou, Shuang Qiao, An-Chun Ji +1
Complete many-body spectra encode thermodynamics, dynamical response, and quantum chaos, yet their exponential size places them beyond enumeration. We introduce tensor-network vari…
