Abstract

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

Evelin Y. Bushuev, Sergey Yu. Kazantsev, E. P. Stroganova +2 more

The article considers a communication system including quantum cryptographic equipment implementing quantum key distribution, in which there is a section of atmospheric optical communication line. The methodology and results of an experimental study of the influence of external nature factors on the efficiency of the communication system using an atmospheric optical communication line are discussed. The research method is based on monitoring the key indicators of the telecommunication channel of the communication network, which determine the quality of the communication system as a whole, such as data transfer rate, error rate, percentage of packet losses. The experiment was conducted on a communication system including a section of atmospheric optical communication line and terminals. The results of the study showed a significant influence of weather factors on the characteristics of the atmospheric optical channel. The data obtained emphasize the need to take into account the influence of external factors in the design and operation of communication systems with an atmospheric optical communication line

Effect of atmospheric discharges on the cryptographic key generation rate in quantum communication systems

O. S. Belova, D. V. Bolotov, Evelin Y. Bushuev +5 more

Subject of study. Technology for quantum key distribution in fiber-optic communication lines under the influence of electromagnetic fields generated by atmospheric discharges is studied. Aim of study. A test bench for testing experimental techniques to be used in studying the effect of atmospheric discharges on transmission of a quantum key via fiber-optic communication lines is developed. Method. The characteristics of a quantum communication channel upon exposure of a coil containing an optical fiber to a magnetic field from a pulsed current are experimentally studied. Main results. An experimental test bench has been created and methods have been developed to evaluate the influence of magnetic fields arising from atmospheric discharges (lightning) on the transmission speed of a quantum key in fiber-optic communication lines. It was shown that quantum key distribution blocks using the BB84 phase-encoding protocol continue to show operational stability when the optical cable is exposed to alternating magnetic fields of up to 1.2 mT. However, the very fact of exposure to magnetic fields above 0.8 mT can be detected by a systematic decrease in the quantum key transmission rate and an increase in the quantum bit error rate (QBER) by 0.5%–1%. Practical significance. The laboratory test bench and methods developed herein support magnetic-field testing of various optical cables used for transmission of qubits. Fiber-optic networks through which qubits are transmitted can serve as a distributed lightning sensor; an increase in the level of quantum errors and a decrease in quantum key generation rate will be observed in any segment of an optical network where a lightning discharge generates strong magnetic fields.

Experimental methods for studying the thunderstorm influence on the operation of fiber optic communication systems

O. S. Belova, A. G. Temnikov, Tatiana Kivshar +8 more

Modern research shows the influence of atmospheric electricity and lightning on the operation of fiber optic communication lines. In particular, such effects can affect the currently developing communication systems protected by quantum key distribution technology. Modern communication systems using quantum key distribution technology can be tuned out from various "slow" external effects caused by thermal or mechanical effects. However, lightning discharges and the strong electromagnetic fields induced by them are capable of exerting an effect in the microsecond range. Since it is difficult to collect the amount of information necessary for analysis using only natural measurements, this paper describes the results of physical modeling of the effect of both lightning discharges and strong electromagnetic fields caused by thunderstorm activity on signals transmitted via optical communication lines.

Joscelin Rabenandrasana, O. V. Kolesnikov, D. V. Bolotov +2 more

The Kerr effect and the Faraday effect are considered for studying the effects of the transverse electric field and the longitudinal magnetic field of lightning in an optical fiber. Presented are experimental study results of electromagnetic fields created by discharges between an artificial thunderstorm cloud and the ground obtained while using the experimental measurement complex “GROZA”. The study results of quantum communication channel and its characteristics, when affected by a magnetic field created by a pulsed current on fiber-optic communication lines are presented. It is demonstrated that an optical cable, through which data protected by quantum key distribution technology is transmitted, can be used as a sensor of alternating magnetic fields, as well as lightning discharges, where transmission characteristics such as reduction of the quantum key transmission rate and QBER increase are used as means of registration.

The Influence of Atmospheric Electricity and Lightning on the Operation of Communication Systems with Quantum Key Distribution

O. S. Belova, D. V. Bolotov, Sergey Yu. Kazantsev +4 more

Abstract The effect of atmospheric electricity on the operation of fiber-optic communication lines has been studied on an electrophysical installation designed to simulate lightning in laboratory conditions. The change in the polarization state of the linearly polarized radiation transmitted over a fiber-optic cable has been measured using a high-speed polarimeter. During the experiments with a frequency of 100 MHz, a change in the polarization state has been monitored. For the first time, rapid rotations of the plane of polarization, the formation of elliptical polarization, and changes in the angle of ellipticity when exposed to atmospheric discharges on an optical cable have been recorded with precise reference. The effect of maintaining the radiation polarization state when the high voltage is turned off at an electrophysical installation has been discovered.
