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…

Memory-assisted measurement-device-independent quantum secret sharing

Cheng Zhang, Qi Zhang, Wei Zhong +6

Measurement-device-independent quantum secret sharing (MDI-QSS) can eliminate all the security loopholes associated with imperfect measurement devices and greatly enhance QS's secu…
