DEVELOPMENT OF A SIMULATION STAND FOR STUDYING THE POLARIZATION STATE OF LASER RADIATION USED IN A QUANTUM COMMUNICATION LINE

Abstract

The introduction of quantum technologies into various fields of science and technology is fueling their rapid development. Ensuring the information security of digital data, in particular, is becoming a priority. Digital data encryption is achieved using the fundamental laws of physics, which led to the development of the quantum key. To understand the processes involved in generating a quantum key in a quantum-optical communication channel, a visual demonstration of the formation of bases is provided. Key generation occurs based on the generated bases, which in turn are determined by the polarization state of the radiation in the communication channel. Developing a simulation rig to determine the polarization state of laser radiation is essential.
