In this paper, we estimate the errors of Gaussian transformations implemented using one-way quantum computations on cluster states of various configurations. From all possible cluster state configurations, we choose those that give the smallest computation error. Furthermore, we evaluate errors in hybrid computational schemes, in which Gaussian operations are performed using one-way computations with additional linear transformations. As a result, we find the optimal strategy for the implementation of universal Gaussian computations with minimal errors.

寻找最佳集群状态配置。最小化单向量子计算错误

在本文中，我们估计了使用单向量子计算对各种配置的集群状态实现的高斯变换的误差。从所有可能的集群状态配置中，我们选择那些给出最小计算误差的配置。此外，我们评估了混合计算方案中的错误，其中高斯运算是使用带有附加线性变换的单向计算来执行的。结果，我们找到了以最小错误实现通用高斯计算的最佳策略。
