Abstract

The embodiment of the invention provides an information transmission method and system based on quantum entanglement. The method comprises the following steps: performing quantum entanglement detection of photons in a first photon group at an information transmitting end and photons in a second photon group at an information receiving end; and if each photon satisfies the quantum entanglement characteristic, transmitting information to be transmitted on the photons modulated into a third photon group to an information receiving end according to the time correlation characteristic between the photons in the third photon group at the local end and the photons in a fourth photon group at the information receiving end. Through adoption of the information transmission method and system, key-free secure transmission is realized, and the problem of hidden danger of keys in saving and management is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular to an information transmission method, device and system based on quantum entanglement. Background technique [0002] In national economic and national defense security communications, important information is often involved. The leakage of these information may cause serious economic losses or bring serious security risks. Therefore, the confidentiality of information in communication is particularly important. [0003] With the continuous development of computer technology, quantum computing has made a breakthrough. Because quantum computing can greatly speed up the cracking speed of traditional encryption methods based on classical cryptography principles, and quantum secure communication technology uses the basic principles of quantum mechanics to achieve physically unbreakable secure communication, quantum secure communication technology has attracted...
