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-…
Reference-frame-independent Quantum secure direct communication
Jia-Wei Ying, Shi-Pu Gu, Xing-Fu Wang +7
Current quantum secure direct communication (QSDC) protocols guarantee communication security by estimating the error rates of photons in the X and Z bases. This take the reference…
Robust hyperentanglement self testing
Yu-Hao Wang, Xing-Fu Wang, Ming-Ming Du +4
Hyperentanglement, which refers to entanglement encoded in two or more independent degrees of freedom (DOFs), is a valuable resource for the future high-capacity quantum network. C…
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…
Fully passive reference frame independent quantum key distribution
Jia-Wei Ying, Shi-Pu Gu, Xing-Fu Wang +2
Reference-frame-independent quantum key distribution (RFI QKD) significantly alleviates alignment requirements for reference frame in practical quantum communication systems. While…
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…
