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…
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…
Generation of concatenated Greenberger-Horne-Zeilinger-type entangled coherent state based on linear optics
Rui Guo, Lan Zhou, Shi-Pu Gu +2
The concatenated Greenberger-Horne-Zeilinger (C-GHZ) state is a new type of multipartite entangled state, which has potential application in future quantum information. In this pap…
