"Quantum" is the general term for the material object that complies with the principles of quantum mechanics. It is the smallest unit that can show the characteristics of a substance or physical quantity. It has indivisible characteristics. For example, photons, atoms, and electrons are the specific manifestations of "quantum"; quantum Mechanics is a theory that studies the laws of physics in the micro world. Its correctness has been gradually confirmed. Studies have shown that the state of micro particles has "intrinsic randomness", that is, their randomness is not caused by a lack of understanding of the system. , But the inherent characteristics of microscopic particles, using this intrinsic randomness, you can generate true random numbers, that is, true random numbers.

The generation process of the true random number cipher is: first, the quantum state preparation module 130 generates a quantum state, which can be a path superposition state of photons; then the measurement module 131 measures the quantum state to collapse the quantum state (equivalent to Mutation), thus forming random measurement data, because the quantum state before measurement can be collapsed to one of several states, according to the state after collapse, the state before collapse cannot be determined, the process is irreversible, and random Measurement data; the data collection module 132 performs high-speed collection of random measurement data; and finally the post-processing module 133 performs post-processing on the collected data, and extracts a true random number therefrom to obtain a true random number password.
