  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.
