Wireless underwater optical communication with quantum key distribution

The results of experimental modeling of a wireless optical communication channel in an aquatic environment are presented, which were carried out on the basis of a laboratory installation for underwater communication, developed at MTUCI. The possibility of creating cheap and compact optical communication systems for high-speed data transmission at distances up to 100 m has been demonstrated. The necessity of using the technology of quantum key distribution for information security is shown. The key elements required for the implementation of the quantum distribution of cryptographic keys in the ocean are analyzed.
