反作用与二态矢量形式

Counterportation and the two-state vector formalism

Justin Dressel, Gregory Reznik, Lev Vaidman

摘要:

哈蒂姆·萨利赫发现了一种传输量子态的方法,在传输通道中不存在粒子,他将其命名为反传。最近[H。Salih,Quantum Sci. 8,025016(2023)],他提出了一种可行的实施方法。Salih采用了Aharonov和Vaidman对该协议的修改,证明了在反向传输期间传输通道中不存在光子的说法。然而,我们认为,这篇论文中有一个错误。一个简化的协议,质疑的有效性的两个状态的矢量形式主义描述的光子存在的通信信道中的分析,是不正确的。

英文摘要:

Hatim Salih discovered a method for transferring a quantum state with no particles present in the transmission channel, which he named counterportation. Recently [H. Salih, Quantum Sci. Technol. 8, 025016 (2023)], 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.
