Inertia of two-qutrit entanglement witnesses
Changchun Feng, Lin Chen, Chang Xu +1
Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We investigate the inertias of bipartite EWs constructed by the partial transpose of NPT stat…
Necessary conditions on effective quantum entanglement catalysts
Yu-Min Guo, Yi Shen, Li-Jun Zhao +4
Quantum catalytic transformations play important roles in the transformation of quantum entangled states under local operations and classical communications (LOCC). The key problem…
Inertias of entanglement witnesses
Yi Shen, Lin Chen, Li-Jun Zhao
Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We study the inertias of EWs, i.e., the triplet of the numbers of negative, zero, and positiv…
Constructions of -uniform states from mixed orthogonal arrays
Fei Shi, Yi Shen, Lin Chen +1
We study -uniform states in heterogeneous systems whose local dimensions are mixed. Based on the connections between mixed orthogonal arrays with certain minimum Hamming distanc…
Absolutely maximally entangled states in tripartite heterogeneous systems
Yi Shen, Lin Chen
Absolutely maximally entangled (AME) states are typically defined in homogeneous systems. However, the quantum system is more likely to be heterogeneous in a practical setup. In th…
Trade-off relation among genuine three-qubit nonlocalities in four-qubit systems
Li-Jun Zhao, Lin Chen, Yu-Min Guo +3
We study the trade-off relations satisfied by the genuine tripartite nonlocality in multipartite quantum systems. From the reduced three-qubit density matrices of the four-qubit ge…
