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…
Network for transfer of an arbitrary -qubit atomic state via cavity QED
Zhan-jun Zhang
I show a scheme which allows a perfect transfer of an unknown single-qubit atomic state from one atom to another by letting two atoms interact simultaneously with a cavity QED. Dur…
Faithful and deterministic teleportation of an arbitrary -qubit state using and identifying only Bell states
Zhan-jun Zhang
First, I show explicitly a scheme to {\it faithfully} and {\it deterministically} teleport an arbitrary 2-qubit state from Alice to Bob. In this scheme two same Bell states are suf…
Economically Improving Message-Unilaterally-Transmitted Quantum Secure Direct Communication to Realize Two-Way Communication
Zhan-jun Zhang, Zhong-xiao Man, Yong Li
We present a subtle idea to economically improve message-unilaterally-transmitted quantum secure direct communication (QSDC) protocols to realize two-way secure direct communicatio…
Less eavesdropping losses induce more eavesdropping information gain
Zhanjun Zhang, Zhongxiao Man, Yong Li
The eavesdropping scheme proposed by Wójcik [Phys. Rev. Lett. {\bf 90},157901(2003)] on the quantum communication protocol of Boström and Felbinger [Phys. Rev. Lett. {\bf 89}, 1879…
Deterministic Secure Direct Bidirectional Communication Protocol
Zhanjun Zhang
In this letter a deterministic secure direct bidirectional communication protocol is proposed by using the quantum entanglement and local unitary operations on one photon of the Ei…
