As shown in fig. 2, a schematic structural diagram of a cross-network transmission box provided in an embodiment of the present application is shown, where the cross-network transmission box includes: a housing and a first cross-network transport structure 9 and a second cross-network transport structure 11 arranged inside the housing.
It should be understood that the shape of the housing shown in fig. 2 is a cube, but the housing may also be a cylinder or other polyhedrons, and the application is not limited thereto.

A quantum channel 16 is arranged between the first cross-network transmission structure 9 and the second cross-network transmission structure 11, and the quantum encryption device 8 transmits data to the quantum decoder 12 through the quantum channel 16.
In fig. 2, the first cross-network transmission structure 9 and the second cross-network transmission structure 11 are both disposed on one surface inside the housing, and it should be understood that the present application does not limit the first cross-network transmission structure 9 and the second cross-network transmission structure 11 to be disposed on the same surface inside the housing, and the first cross-network transmission structure 9 and the second cross-network transmission structure 11 may be disposed at any position inside the housing without affecting quantum transmission.
The quantum transmission is mainly based on the theory of quantum entanglement state, the information transmission is realized by using a quantum invisible state transmission mode, a quantum channel 16 in the quantum transmission can be an air medium and the like, the quantum channel 16 infinitely determines that the quantum transmission does not limit the data transmission capacity, and more encrypted data can be transmitted to the quantum decoder 12 through the quantum channel 16.

For example, when the data type is sound, the sound is propagated in the form of wave vibration, the amplitude of the sound wave is represented by a binary code, and here, the amplitude naming binary rule needs to be customized in advance, and then the data type can be converted into a binary.
For example, when the data type is video or picture, the video is divided into frames, each frame picture is composed of a certain amount of pixel points, and the information worth of each pixel point is converted into binary data.
