Nicolas C. Menicucci, Peter van Loock, Mile Gu, Christian Weedbrook, Timothy C. Ralph, Michael A. Nielsen

摘要:

我们描述了一个概括的集群状态模型的量子计算连续变量系统,以及一个建议的光学实现使用挤压光源,线性光学,和零差检测。对于通用量子计算,需要非线性元件。这可以通过在工具箱中添加任何单模非高斯测量来满足,而初始集群状态本身仍然是高斯的。仅零差检测就足以通过团簇状态执行任意多模高斯变换。我们还提出了一个实验来证明基于聚类的错误减少时,实施高斯运算。

英文摘要:

We describe a generalization of the cluster-state model of quantum computation to continuous-variable systems, along with a proposal for an optical implementation using squeezed-light sources, linear optics, and homodyne detection. For universal quantum computation, a nonlinear element is required. This can be satisfied by adding to the toolbox any single-mode non-Gaussian measurement, while the initial cluster state itself remains Gaussian. Homodyne detection alone suffices to perform an arbitrary multi-mode Gaussian transformation via the cluster state. We also propose an experiment to demonstrate cluster-based error reduction when implementing Gaussian operations.
