Coherence Control of Adiabatic Decoherence in a Three-level Atom with Lambda Configuration
Xiao-Shu Liu, Wu Re-bing, Yang Liu +2
In this paper, we study the suppression of adiabatic decoherence in a three-level atom with configuration using bang-bang control technique. We have given the decoupling bang-b…
A Two-Step Quantum Direct Communication Protocol Using Einstein-Podolsky-Rosen Pair Block
Fu-Guo Deng, Gui Lu Long, Xiao-Shu Liu
A protocol for quantum secure direct communication using blocks of EPR pairs is proposed. A set of ordered EPR pairs is used as a data block for sending secret message directly…
Entanglement in a two-identical-particle system
Yan Song Li, Bei Zeng, Xiao Shu Liu +1
The definition of entanglement in identical-particle system is introduced. The separability criterion in two-identical particle system is given. The physical meaning of the definit…
Theoretical efficient high capacity Quantum Key Distribution Scheme
Gui Lu Long, Xiao Shu Liu
A theoretical quantum key distribution scheme using EPR pairs is presented. This scheme is efficient in that it uses all EPR pairs in distributing the key except those chosen for c…
