Non-static Quantum Bit Commitment
Jeong Woon Choi, Dowon Hong, Ku-Young Chang +2
Quantum bit commitment has been known to be impossible by the independent proofs of Mayers, and Lo and Chau, under the assumption that the whole quantum states right before the unv…
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…
