摘　　要：树型三维纠缠态是一种新型的三维纠缠态,其可增强量子通信的安全性.基于囚禁离子系统提出一种只需一步就可制备三离子树型三维纠缠态的理论方案.该方案所需的相互作用时间短,基于当前的技术是有可能实现的.A novel three-dimensional entangled state called tree-type three-dimensional entanglement is likely to have applications for improving quantum communication security. A one-step theoretical scheme is proposed for preparing a tree-type three-dimensional entangled state via trapped ions. In the scheme,the required interaction time is very short. The present proposal may be realized based on the current technologies.
