Robust logical Bell nonlocality based on quantum error correction codes
Qi Zhang, Jia-Wei Ying, Cheng Liu +2
Quantum nonlocality based on the violation of Bell-like inequalities constitutes a fundamental feature of quantum physics and drives the development of device-independent (DI) quan…
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-efficiency and long-distance quantum memory-assisted device-independent quantum secret sharing with single photon sources
Qi Zhang, Jia-Wei Ying, Shi-Pu Gu +5
Quantum secret sharing (QSS) plays a critical role in building the distributed quantum networks. Device-independent (DI) QSS provides the highest security level for QSS. However, t…
Quantum secure direct communication based on fully passive source
Jia-Wei Ying, Qi Zhang, Shi-Pu Gu +3
In practical quantum communication, imperfect devices may introduce side channels, creating opportunities for eavesdroppers. Especially on the source side, the side channels create…
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…
