Comment on “Bidirectional Quantum Teleportation of Two-Qubit State Via Four-Qubit Cluster State”
In this comment, it is shown that the scheme recently proposed by Zhou et al. [Int. J. Theor. Phys. 58, 150 (2019)] for bidirectional quantum teleportation of two-qubit entangled state by using four-qubit cluster state is incorrect and in their proposed scheme, a four-qubit cluster state cannot be u...

| Zusammenfassung: | In this comment, it is shown that the scheme recently proposed by Zhou et al. [Int. J. Theor. Phys. 58, 150 (2019)] for bidirectional quantum teleportation of two-qubit entangled state by using four-qubit cluster state is incorrect and in their proposed scheme, a four-qubit cluster state cannot be used as a quantum channel for successful realization of bidirectional quantum teleportation. |
