A low order Bargmann invariant hierarchy for set coherence
Yan-Ling Wang
Set coherence is a basis-independent relational form of quantum coherence: a finite family of quantum states is set incoherent exactly when all its members are diagonal in one comm…

Simultaneous Detection of High-Dimensional Entanglement for Two Unknown Quantum States
Mao-Sheng Li, Chang-Yue Zhang, Zheng Zheng +7
The state overlap, quantified via $\tr[ÏÏ]$, is a metric widely used to assess the closeness between two quantum states and . Although global state overlap alone does no…
