Efficient quantum cryptography network without entanglement and quantum memory
Chun-Yan Li, Xi-Han Li, Fu-Guo Deng +3
An efficient quantum cryptography network protocol is proposed with d-dimension polarized photons, without resorting to entanglement and quantum memory. A server on the network, sa…
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…
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…
Quantum secure direct communication with quantum encryption based on pure entangled states
Xi-Han Li, Chun-Yan Li, Fu-Guo Deng +3
We present a scheme for quantum secure direct communication with quantum encryption. The two authorized users use repeatedly a sequence of the pure entangled pairs (quantum key) sh…
Eavesdropping on the "Ping-Pong" Quantum Communication Protocol Freely in a Noise Channel
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
We introduce an attack scheme for eavesdropping the ping-pong quantum communication protocol proposed by Bostrm and Felbinger [Phys. Rev. Lett. \textbf{89}, 187902 (2002)…
