Circular quantum secret sharing
Fu-Guo Deng, Hong-Yu Zhou andGui Lu Long
A circular quantum secret sharing protocol is proposed, which is useful and efficient when one of the parties of secret sharing is remote to the others who are in adjacent, especia…
Multiparty Quantum Remote Secret Conference
Xi-Han Li, Chun-Yan Li, Fu-Guo Deng +3
We present two schemes for multiparty quantum remote secret conference in which each legitimate conferee can read out securely the secret message announced by another one, but a vi…
Improving the security of secure direct communication based on secret transmitting order of particles
Xi-Han Li, Fu-Guo Deng, Hong-Yu Zhou
We analyzed the security of the secure direct communication protocol based on secret transmitting order of particles recently proposed by Zhu, Xia, Fan, and Zhang [Phys. Rev. A 73,…
Quantum Entanglement of Electromagnetic Fields in Non-inertial Reference Frames
Yi Ling, Song He, Weigang Qiu +1
Recently relativistic quantum information has received considerable attention due to its theoretical importance and practical application. Especially, quantum entanglement in non-i…
Multiparty Quantum Secret Report
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +3
A multiparty quantum secret report scheme is proposed with quantum encryption. The boss Alice and her agents first share a sequence of (+1)-particle Greenberger--Horne--Zeil…
Economical Quantum Secure Direct Communication Network with Single Photons
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
A scheme for quantum secure direct communication (QSDC) network is proposed with a sequence of polarized single photons. The single photons are prepared originally in the same stat…
