论文摘要
量子因果关系通过允许通道和操作以不确定的因果秩序作用来扩展固定因果结构的常规概念。这种不确定的因果秩序的重要性范围从基础 - 例如。迈向量子重力理论---对所应用的---例如。对于通信和计算方面的优势。在这篇综述中，我们将介绍无限因果秩序的基本理论，并专注于依靠物理上可实现的无限因果有序过程的实验 - 量子开关。
Quantum causality extends the conventional notion of fixed causal structure by allowing channels and operations to act in an indefinite causal order. The importance of such an indefinite causal order ranges from the foundational---e.g. towards a theory of quantum gravity---to the applied---e.g. for advantages in communication and computation. In this review, we will walk through the basic theory of indefinite causal order and focus on experiments that rely on a physically realisable indefinite causal ordered process---the quantum switch.
