含噪声团簇态的量子信息处理

Quantum information processing with noisy cluster states

M. S. Tame, M. Paternostro, M. S. Kim, V. Vedral

摘要:

我们提供了一个分析的基本量子信息处理协议的影响下的集群状态的内在非理想性。这些非理想性是基于在创建团簇状态的纠缠步骤中引入随机性,并且是由使用凝聚态系统创建纠缠时所面临的不可避免的缺陷所激发的。借助于一种替代的和非常有效的方法来构建集群状态配置,这依赖于级联的基本集群结构,我们解决量子态转移和各种基本门模拟通过噪声集群状态。我们发现,一个成功的策略,以限制噪声的影响,是通过几个测量处理的小集群的管理。我们的研究还加强了最近与单向量子计算机的光学实现相关的想法。

英文摘要:

We provide an analysis of basic quantum information processing protocols under the effect of intrinsic non-idealities in cluster states. These non-idealities are based on the introduction of randomness in the entangling steps that create the cluster state and are motivated by the unavoidable imperfections faced in creating entanglement using condensed-matter systems. Aided by the use of an alternative and very efficient method to construct cluster state configurations, which relies on the concatenation of fundamental cluster structures, we address quantum state transfer and various fundamental gate simulations through noisy cluster states. We find that a winning strategy to limit the effects of noise, is the management of small clusters processed via just a few measurements. Our study also reinforces recent ideas related to the optical implementation of a one-way quantum computer.
