Quantifying and Probing Multipartite Entanglement via Minimum Entanglement Drop
Dong-Dong Dong, Xue-Ke Song, Liu Ye +1
Quantifying genuine multipartite entanglement remains a significant challenge. We propose a multipartite entanglement monotone defined by the minimum entanglement drop -- the reduc…

Maximum residual strong monogamy inequality for multiqubit entanglement
Dong-Dong Dong, Xue-Ke Song, Liu Ye +2
We establish two new inequalities, the weighted strong monogamy (WSM) and the maximum residual strong monogamy (MRSM), which sharpen the generalized Coffman-Kundu-Wootters inequity…

Quantifying genuine tripartite entanglement by reshaping the state
Dong-Dong Dong, Li-Juan Li, Xue-Ke Song +2
Although genuine multipartite entanglement (GME), as one quantum resource, is indispensable in quantum information processing, most of the existing measures cannot detect GME faith…
