Quantum secure direct communication network with Einstein-Podolsky-Rosen pairs
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
We discuss the four requirements for a real point-to-point quantum secure direct communication (QSDC) first, and then present two efficient QSDC network schemes with an N ordered E…
Improving the security of multiparty quantum secret sharing against Trojan horse attack
Fu-Guo Deng, Xi-Han Li, Hong-Yu Zhou +1
We analyzed the security of the multiparty quantum secret sharing (MQSS) protocol recently proposed by Zhang, Li and Man [Phys. Rev. A \textbf{71}, 044301 (2005)] and found that th…
Multiparty quantum state sharing of an arbitrary two-particle state with Einstein-Podolsky-Rosen pairs
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
A scheme for multiparty quantum state sharing of an arbitrary two-particle state is presented with Einstein-Podolsky-Rosen pairs. Any one of the agents has the access to regene…
Symmetric multiparty-controlled teleportation of an arbitrary two-particle entanglement
Fu-Guo Deng, Chun-Yan Li, Yan-Song Li +2
We present a way for symmetric multiparty-controlled teleportation of an arbitrary two-particle entangled state based on Bell-basis measurements by using two Greenberger-Horne-Zeil…
