◎講 題(Topic)：Separability from Multipartite Measures
◎日 期與時間(Date/Time)：115年9月23日(三) 13:00~
PM13:00 Wed., Sep. 23, 2026
◎地點( Place)：育成中心3-2 Incubation Center 3-2
◎邀請者(Host)：葉振斌教授 Prof. Yung-Kang Kuo
◎摘要(Abstract)：
We show that multi-invariants provide necessary and sufficient criteria for full separability in finite-dimensional multipartite systems.
For tripartite three-qubit states, the third-order negativity gives an exact criterion for full separability for both pure and mixed states.
We then extend the framework to four-qubit pure states, whose full characterization requires six bipartite, eight tripartite, and four quadripartite measures, with the third-order negativity serving as a key separability criterion.
Finally, we generalize the construction to multipartite qudit systems and discuss an application to conformal field theory.
