Variational quantum algorithm for generalized eigenvalue problems of non-Hermitian systems
Jiaxin Li, Zhaobing Fan, Hongmei Yao +5
Non-Hermitian generalized eigenvalue problems (GEPs) play a significant role in many practical applications, such as mechanical engineering. Based on the generalized Schur decompos…

Quantum entanglement estimation via symmetric measurement based positive maps
Jiaxin Li, Hongmei Yao, Shao-Ming Fei +2
We provide a class of positive and trace-preserving maps based on symmetric measurements. From these positive maps we present separability criteria, entanglement witnesses, as well…

Biderivations of Hom-Lie algebras and superalgebras
Lamei Yuan, Jiaxin Li
On Hom-Lie algebras and superalgebras,we introduce the notions of biderivations, linear commuting maps and α-biderivations, and compute them for some typical Hom-Lie algebras and s…
