Optical Quantum Technologies

Yangyi Zheng

Due to the advancement of technology, laser communication, fiber optic communication and optical quantum communication have been developed, not only in the field of life, but also in the field of aviation, military and information security. This paper, mainly compares the difference between optical quantum communication and other communication technologies in terms of security and effectiveness, presenting the current state of technology and applications and providing an outlook on future directions. Through the comparison, this paper argues that the application of technology in optical quantum communication can promote the rapid development of quantum communication technology and thus enhance the comprehensive strength of global communication technology.
