摘　　要：首先利用几类二维基本结构,给出链状三维簇态的制备方案.随后将二维基本结构扩展到三维,由此可以构建任意三维簇态.最后,提出两类新的基本结构,并由此实现一类特殊三维簇态的制备.所有制备方案都是基于交叉相位调制技术,比之此前的方案,具有可以确定性、高效性、快速性三大优点,使得簇态的制备对量子存储器的依赖得到很大程度的缓解,更具可行性和更加适用于大规模量子计算.Based on the former structures in the generation of two-dimensional cluster states,we first propose a scheme to generate linear three-dimensional （3D） cluster state. After that,we develop the former structures to three-dimension,and then we could use them to generate universal 3D cluster states. In final,we provide two new structures,which could make the generation of a special type of 3D cluster state very efficient. All the proposals work with cross-phase modulation,so they are deterministic,highly efficient,fast,compared with the former schemes. It will make the requirement of quantum memory much relax,thus it is more feasible and suitable for large-scale one-way quantum computation.
