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 $n$ -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 $N$ -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…
