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…
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…
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…
