摘要
在最近的一篇论文中,格里菲斯[物理学家]。Rev. A 107, 062219(2023)]分析了Salih等人引入的双方信息传输协议。生物工程学报,2011,27(2)。关于该协议的反事实性存在相当大的争议,Griffiths建议通过引入一种新的通道使用度量来解决这个问题,他称之为“成本”。“我认为这一措施是不合适的,因为根据这一措施,触发反事实概念定义的原始无交互测量协议并不是反事实的。
Comment on “Multitime quantum communication: Interesting but not counterfactual”
In a recent paper, Griffiths [Phys. Rev. A 107, 062219 (2023)] analyzed a protocol for transmission of information between two parties introduced by Salih et al. [Phys. Rev. Lett. 110, 170502 (2013)]. There is a considerable controversy about the counterfactuality of this protocol, and Griffiths suggested to resolve it by introducing a new measure of channel usage, which he called ``Cost.'' I argue that this measure is not appropriate because the original interaction-free measurement protocol which triggered the definition of the concept of counterfactuality is not counterfactual according to this measure.
