Forgeable quantum messages in arbitrated quantum signature schemes
Taewan Kim, Hyang-Sook Lee, Soojoon Lee
Recently, the concept on `forgeable quantum messages' in arbitrated quantum signature schemes was introduced by T. Kim et al. [Phys. Scr., 90, 025101 (2015)], and it has been shown…
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…
Three-party d-level quantum secret sharing protocol
Dong Pyo Chi, Jeong Woon Choi, Jeong San Kim +2
We develop a three-party quantum secret sharing protocol based on arbitrary dimensional quantum states. In contrast to the previous quantum secret sharing protocols, the sender can…
