Applicability of quantum key distribution technology under free-space atmospheric conditions to construct segments of modern quantum communication networks

Kirill Yu. Erokhin, Sergey Yu. Kazantsev, T. V. Kazieva +2 more

Subject of study. This study examined the applicability of quantum key distribution (QKD) technology under free-space atmospheric conditions. Aim of study. The objective was the development of a hardware and software system for investigating the applicability of QKD technology in wireless communication systems based on commercially available modules. The system includes optical blocks for atmospheric optical communication and a training setup for studying QKD in fiber-optic communication lines. Method. The characteristics of a quantum communication channel in free-space conditions were studied through experiments. The channel was formed by the QKD units of the EMQOS 1.0 scientific and educational complex, integrated with optical blocks for atmospheric optical communication. The systems were also upgraded to minimize losses in the quantum channel. Main results. A hardware and software system was developed, within which the transmission of a quantum key through free-space atmospheric conditions over a distance of 180 m was successfully demonstrated. The quantum bit error rate did not exceed 6%. This system enabled the study of the effects of weather conditions on optical losses in the quantum communication channel and the quantum key generation rate. Practical significance. The developed hardware and software system allows the monitoring of the parameters of both classical and quantum communication channels in free space under various weather conditions. Its modular structure enables the integration of other quantum equipment for comparative testing of the performance of quantum communication systems under real atmospheric transmission conditions.

Fiber-Optic Communication System Operation Under Electromagnetic Fields Influence

S. E. Grychkin, Evelin Y. Bushuev, D. V. Bolotov +2 more

The article studies the influence of electromagnetic influence on a fiber-optic communication system with quantum cryptographic equipment. The developed test benches and methods of experimental study of the influence of electromagnetic effects on a communication system with quantum cryptographic equipment with fiber-optic communication line are presented. The results of experimental study of electromagnetic influence on the communication system with quantum key distribution and an optical cable are discussed. The results of studying showed that the influence of magnetic fields on the transmission of an optical signal through an optical fiber leads to a significant rotation of the plane of polarization, and therefore to errors and failures in the system with quantum key distribution. At the same time, the experiment showed that the influence of electric fields is insignificant. The obtained data emphasize the need to take into account the electromagnetic environment when designing and operating communication systems with a fiber-optic communication line

A laboratory setup has been created that makes it possible to conduct comprehensive studies of the influence of atmospheric discharges on the transmission of quantum keys over optical communication lines. The effect of a strong action of an electric field from a charged water aerosol on the polarization of radiation passing along an all-dielectric fiber-optic cable has been found. The dynamics of changes in the optical fiber arising from the action of electrostatic fields of a charged cloud, preceding the electrical breakdown of air, has been registered. An analysis of the need to protect quantum networks from the effects of atmospheric discharges is presented.
