论文摘要
因果关系的识别是科学方法的基石。该任务的传统方法基于经典统计。但是，这种经典方法并不适用于量子域，在量子域中，更广泛的因果关系变得可以访问。近年来已经开发了量子因果推断的新方法，并发现了有希望的新功能。在本文中，我们审查并部分扩展了参考文献的框架和结果。 [1]，在识别可逆过程引起的各种因果关系中证明了量子加速。
The identification of causal relations is a cornerstone of the scientific method. Traditional approaches to this task are based on classical statistics. However, such classical approaches do not apply in the quantum domain, where a broader spectrum of causal relations becomes accessible. New approaches to quantum causal inference have been developed in recent years, and promising new features have been discovered. In this paper, we review and partly expand the framework and results of Ref. [1], which demonstrated quantum speedups in the identification of various types of causal relations induced by reversible processes.
