Large Scale Entanglement Structure Detection in 100-Qubit Systems via Local Joint Measurements
Rui Li, Yuhang Wang, Chunxiao Du +5
Identifying the entanglement structure of a many-body quantum state, namely how its constituents partition into unentangled blocks, is a central task in quantum information science…
An Exponential Advantage for Adaptive Tomography of Structured States under Pauli Basis Measurements
Alireza Goldar, Zhen Qin, Zhihui Zhu +2
Broad claims about whether adaptivity helps in quantum state tomography can be misleading unless the state family, measurement architecture, and error metric are specified carefull…
Calibrating the Role of Entanglement in Variational Quantum Algorithms from a Geometric Perspective
Chunxiao Du, Yang Zhou, Zhichen Huang +4
Calibrating the role of entanglement in quantum algorithms is a crucial task in the development of quantum computing. Most existing studies have primarily focused on how the static…
Diffusion-Enhanced Optimization of Variational Quantum Eigensolver for General Hamiltonians
Shikun Zhang, Zheng Qin, Yongyou Zhang +4
Variational quantum algorithms (VQAs) have emerged as a promising approach for achieving quantum advantage on current noisy intermediate-scale quantum devices. However, their large…
High-dimentional Multipartite Entanglement Structure Detection with Low Cost
Rui Li, Shikun Zhang, Zheng Qin +3
