摘要:

Kitaev模型既有阿贝尔激发又有非阿贝尔激发。它可以作为拓扑量子计算的起点。然而,这个模型的哈密顿量是很难实现的自然凝聚态系统。本文提出了一种量子模拟方案,通过构造耦合腔晶格中的Kitaev模型哈密顿量,其中腔中嵌入了$Λ$型三能级原子。在该方案中,几个参数是可调的,例如,通过外部激光场。重要的是,我们的计划是基于目前现有的技术,它提供了一个可行的方式实现Kitaev模型探索拓扑激发。

英文摘要:

Kitaev model has both Abelian and non-Abelian anyonic excitations. It can act as a starting point for topological quantum computation. However, this model Hamiltonian is difficult to implement in natural condensed matter systems. Here we propose a quantum simulation scheme by constructing the Kitaev model Hamiltonian in a lattice of coupled cavities with embadded $Λ$-type three-level atoms. In this scheme, several parameters are tunable, for example, via external laser fields. Importantly, our scheme is based on currently existing technologies and it provides a feasible way of realizing the Kitaev model to explore topological excitations.
