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…
