Efficient symmetric multiparty quantum state sharing of an arbitrary m-qubit state
Xi-Han Li, Ping Zhou, Chun-Yan Li +2
We present a scheme for symmetric multiparty quantum state sharing of an arbitrary -qubit state with Greenberger-Horne-Zeilinger states following some ideas from the control…
On the Quantum Mechanics for One Photon
Yapeng Hu, Weigang Qiu, Hongbao Zhang
This paper revisits the quantum mechanics for one photon from the modern viewpoint and by the geometrical method. Especially, besides the ordinary (rectangular) momentum representa…
Quantum state sharing of an arbitrary two-qubit state with two-photon entanglements and Bell-state measurements
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
Two schemes for sharing an arbitrary two-qubit state based on entanglement swapping are proposed with Bell-state measurements and local unitary operations. One is based on the quan…
Multiparty quantum secret splitting and quantum state sharing
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
A protocol for multiparty quantum secret splitting is proposed with an ordered EPR pairs and Bell state measurements. It is secure and has the high intrinsic efficiency and sou…
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…
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)…
