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…
Observation of quantum information collapse-and-revival in a strongly-interacting Rydberg atom array
De-Sheng Xiang, Yao-Wen Zhang, Hao-Xiang Liu +8
Interactions of isolated quantum many-body systems typically scramble local information into the entire system and make it unrecoverable. Ergodicity-breaking systems possess the po…
