Tight Trade-off Between Internal, Assisted, and External Entanglement
Limin Gao, Chenxiao Wang
We derive a tight and saturable monogamy relation for three-qubit pure states that bounds the sum of concurrence and concurrence of assistance by the entanglement with an external…

Entanglement-Assisted Discrimination of Nonlocal Sets of Orthogonal States
Ziying Hou, Huaqi Zhou, Limin Gao
Entanglement-assisted discrimination of orthogonal quantum states exhibiting quantum nonlocality is a frontier topic in quantum information theory. In this paper, we investigate th…

Tighter monogamy and polygamy relations in multiparty quantum systems
Chenxiao Wang, Limin Gao
The monogamy and polygamy properties of quantum entanglement characterize fundamental constraints on the distribution of entanglement in multipartite quantum systems. In this paper…
