High-capacity dual degrees of freedom quantum secret sharing protocol beyond the linear rate-distance bound
Meng-Dong Zhu, Cheng Zhang, Shi-Pu Gu +5
Quantum secret sharing (QSS) is the multipartite cryptographic primitive. Most of existing QSS protocols are limited by the linear rate-distance bound, and cannot realize the long-…
High-efficient long-distance device-independent quantum secret sharing based on single-photon sources
Qi Zhang, Cheng Zhang, Wei Zhong +3
Device-independent quantum secret sharing (DI QSS) relaxes security assumptions of experimental devices to provide the highest security level for QSS. Previous DI QSS protocols req…
Efficient hyperentanglement-based quantum secret sharing protocol
Cheng Zhang, Fu-Le Hao, Shi-Pu Gu +3
Quantum secret sharing (QSS) is a typical multipartite cryptographic primitive, which is an important part of quantum communication network. Existing QSS protocols generally requir…
Receiver-device-independent quantum secure direct communication
Cheng Liu, Cheng Zhang, Shi-Pu Gu +3
Quantum secure direct communication (QSDC) enables the message sender to directly send secure messages to the receiver through the quantum channel without keys. Device-independent…
