Any multipartite entangled state violating Mermin-Klyshko inequality can be distilled for almost all bipartite splits
Soojoon Lee, Jinhyoung Lee, Jaewan Kim
We study the explicit relation between violation of Bell inequalities and bipartite distillability of multi-qubit states. It has been shown that even though for there exis…

Quantum states for perfectly secure secret sharing
Dong Pyo Chi, Jeong Woon Choi, Jeong San Kim +2
In this work, we investigate what kinds of quantum states are feasible to perform perfectly secure secret sharing, and present its necessary and sufficient conditions. We also show…

Monogamy equality in quantum systems
Dong Pyo Chi, Jeong Woon Choi, Kabgyun Jeong +3
There is an interesting property about multipartite entanglement, called the monogamy of entanglement. The property can be shown by the monogamy inequality, called the Coffman-Kund…
