Visualization of all two-qubit states via partial-transpose-moments
Lin Zhang, Yi Shen, Hua Xiang +2
Efficiently detecting entanglement based on measurable quantities is a basic problem for quantum information processing. Recently, the measurable quantities called partial-transpos…
Determining system Hamiltonian from eigenstate measurements without correlation functions
Shi-Yao Hou, Ningping Cao, Sirui Lu +3
Local Hamiltonians arise naturally in physical systems. Despite its seemingly `simple' local structure, exotic features such as nonlocal correlations and topological orders exhibit…
A Separability-Entanglement Classifier via Machine Learning
Sirui Lu, Shilin Huang, Keren Li +7
The problem of determining whether a given quantum state is entangled lies at the heart of quantum information processing, which is known to be an NP-hard problem in general. Despi…
Geometry of reduced density matrices for symmetry-protected topological phases
Ji-Yao Chen, Zhengfeng Ji, Zheng-Xin Liu +2
In this paper, we study the geometry of reduced density matrices for states with symmetry-protected topological (SPT) order. We observe ruled surface structures on the boundary of…
Discontinuity of Maximum Entropy Inference and Quantum Phase Transitions
Jianxin Chen, Zhengfeng Ji, Chi-Kwong Li +5
In this paper, we discuss the connection between two genuinely quantum phenomena --- the discontinuity of quantum maximum entropy inference and quantum phase transitions at zero te…
