Bargmann-invariant framework for local unitary equivalence and entanglement
Lin Zhang, Bing Xie, Yuanhong Tao
Research on quantum states often focuses on the correlation between nonlocal effects and local unitary invariants, among which local unitary equivalence plays a significant role in…

Geometry of sets of Bargmann invariants
Lin Zhang, Bing Xie, Bo Li
Certain unitary-invariants, known as Bargmann invariants or multivariate traces of quantum states, have recently gained attention due to their applications in quantum information t…
