Hatim Salih discovered a method for transferring a quantum state with no particles present in the transmission channel, which he named counterportation. Recently (Salih 2023 Quantum Sci. Technol. 8 025016), he presented a feasible procedure for its implementation. The modification of the protocol by Aharonov and Vaidman, adopted by Salih, justifies the claim that no photons were present in the transmission channel during counterportation. We argue, however, that there is an error in this paper. The analysis of a simplified protocol, which questions the validity of the two-state vector formalism description of the photon presence in the communication channel, is incorrect.

对“从反传送到本地虫洞”的评论

哈蒂姆·萨利赫发现了一种在传输通道中不存在粒子的情况下转移量子态的方法，他将其命名为反传态。最近（萨利赫 2023量子科学。技术。 8025016），他提出了可行的实施程序。阿哈罗诺夫和瓦伊德曼对协议的修改并被萨利赫采用，证明了反传期间传输通道中不存在光子的说法是正确的。然而，我们认为本文存在错误。对简化协议的分析质疑通信通道中光子存在的二态矢量形式描述的有效性，这是不正确的。
