Ryan J. Marshman, Austin P. Lund, Peter P. Rohde, Timothy C. Ralph

摘要:

提出并研究了一种利用酉平均方法对玻色线性网络进行检错和噪声校正的方法。所提出的误差平均不依赖于辅助光子或控制和前馈校正电路,在其操作中保持完全被动。我们构建了一个通用的数学框架,这种技术,然后给出了一系列的证明原则的例子,包括数值分析。两种方法的建设,平均值进行比较,以确定最有效的实施方式和探测相关的错误阈值。最后,我们讨论了这个计划的一些潜在用途。

英文摘要:

We propose and investigate a method of error detection and noise correction for bosonic linear networks using a method of unitary averaging. The proposed error averaging does not rely on ancillary photons or control and feed-forward correction circuits, remaining entirely passive in its operation. We construct a general mathematical framework for this technique then give a series of proof of principle examples including numerical analysis. Two methods for the construction of averaging are then compared to determine the most effective manner of implementation and probe the related error thresholds. Finally we discuss some of the potential uses of this scheme.
