Communication Method Regarding Quantum Teleportation as Quantum Channel
The classical one-time-pad communication method exhibits the disadvantage of key loss and the shortcoming that the key will be quickly exhausted when a large amount of data is transmitted, making it unsuitable for classical big data communication. Further, it is difficult to distinguish the four Bell states in quantum teleportation. This study considers quantum teleportation as a quantum channel that transmits classical information sequences because quantum channels not only transmit quantum information but also classical information. The transmitted data 0 and 1 are encoded as quantum states |0> and |1>, respectively. The proposed scheme can continuously ensure security and generate keys, which is suitable for big data communication. Furthermore, this scheme only needs to distinguish between two kinds of Bell states, which can be easily implemented.
