Quantum secure direct communication without using perfect quantum channel
Jian Wang, Quan Zhang, Chao-jing Tang
Most of the quantum secure direct communication protocol needs a pre-established secure quantum channel. Only after insuring the security of quantum channel, could the sender encod…
Quantum signature scheme with single photons
Jian Wang, Quan Zhang, Chao-jing Tang
Quantum digital signature combines quantum theory with classical digital signature. The main goal of this field is to take advantage of quantum effects to provide unconditionally s…
Efficient multiparty quantum secret sharing of secure direct communication
Jian Wang, Quan Zhang, Chao-jing Tang
In this paper, we present an (n, n) threshold quantum secret sharing scheme of secure direct communication using Greenberger-Horne-Zeilinger state. The present scheme is efficient…
Quantum key distribution protocols using entangled state
Jian Wang, Quan Zhang, Chao-jing Tang
We present three quantum key distribution protocols using entangled state. In the first two protocols, all Einstein-Podolsky-Rosen pairs are used to distribute a secret key except…
