线性光学量子计算中模式失配的误差模型

Error models for mode-mismatch in linear optics quantum computing

Peter P. Rohde, Timothy C. Ralph

摘要:

线性光学量子计算(LOQC)发展面临的最重大挑战之一是模式失配,由此在电路内引入光子可分辨性,破坏量子干涉效应。我们研究的奇偶校验(或融合)门,在最近的几个LOQC计划的基本积木模式失配的影响。我们推导出简单的误差模型的模式不匹配对其操作的影响,并将这些误差模型与当前的容错阈值估计。

英文摘要:

One of the most significant challenges facing the development of linear optics quantum computing (LOQC) is mode-mismatch, whereby photon distinguishability is introduced within circuits, undermining quantum interference effects. We examine the effects of mode-mismatch on the parity (or fusion) gate, the fundamental building block in several recent LOQC schemes. We derive simple error models for the effects of mode-mismatch on its operation, and relate these error models to current fault tolerant threshold estimates.
