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…
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…
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…
Fully passive quantum key distribution with parametric down-conversion source
Jia-Wei Ying, Qi Zhang, Shi-Pu Gu +3
The fully passive source is capable of passively generating decoy states and performing passive encoding simultaneously, avoiding the side-channel risks caused by active modulation…
