Faithful geometric measures for genuine tripartite entanglement

X Ge, L Liu, Y Wang, Y Xiang, G Zhang, L Li, S Cheng - Physical Review A, 2024 - APS
We present a faithful geometric picture for genuine tripartite entanglement of discrete,
continuous, and hybrid quantum systems. We first find that the triangle relation E i| jk α≤ E j …

Hermitian tensor decompositions

J Nie, Z Yang - SIAM Journal on Matrix Analysis and Applications, 2020 - SIAM
Hermitian tensors are generalizations of Hermitian matrices, but they have very different
properties. Every complex Hermitian tensor is a sum of complex Hermitian rank-1 tensors …

The geometric measure of entanglement of multipartite states and the Z-eigenvalue of tensors

L Xiong, J Liu, Q Qin - Quantum Information Processing, 2022 - Springer
It is not easy to compute the entanglement of multipartite pure or mixed states, because it
usually involves complex optimization. In this paper, we are devoted to the geometric …

Hermitian tensor and quantum mixed state

G Ni - arXiv preprint arXiv:1902.02640, 2019 - arxiv.org
An order $2 m $ complex tensor $\cH $ is said to be Hermitian if\[\mathcal {H} _\ijm=\mathcal
{H} _\jim^*\mathrm {\for\all\}\ijm.\] It can be regarded as an extension of Hermitian matrix to …

Separability of Hermitian tensors and PSD decompositions

M Dressler, J Nie, Z Yang - Linear and Multilinear Algebra, 2022 - Taylor & Francis
Hermitian tensors are natural generalizations of Hermitian matrices, while possessing rather
different properties. A Hermitian tensor is separable if it has a Hermitian decomposition with …
