Optical Fiber Data Throughput In A Quantum Communication System

Arash Kosari, Ali Araghi

Published Jan 2, 2018• 0 citations
Publisher

Abstract

A mathematical model for an optical-fiber communication channel is developed which results in an expression that calculates the throughput and loss of the corresponding link. The data are assumed to be transmitted by using of separate photons with different polarizations. The derived model also shows the dependency of data throughput with length of the channel and depolarization factor. It is observed that absorption of photons affects the throughput in a more intensive way in comparison with that of depolarization. Apart from that, the probability of depolarization and the absorption of radiated photons are obtained.

DATA THroughput OF OPTIC FIBERin quantum communications system

Иван Романович Гулаков, A. O. Zenevich, A. M. Timofeev

A mathematical model of communications channel that transfers data by means of separate photons having different polarization has been developed. The expression for calculating of optic fiber throughput has been obtained that takes into account probabilities of depolarization and absorption of radiation photon. As a result of implemented simulation it has been found that data throughput depends on the length of optic fiber. It has been established that photon absorption as compared with its depolarization contributes greatly to the size of optic fiber throughput.

Analysis of polarization mode dispersion effect on quantum state decoherence in fiber-based optical quantum communication

Shamsolah Salemian, Shahram Mohammadnejad

The implementation of quantum communication protocols in long optical fibers is limited by several decoherence mechanisms. In this contribution we review this mechanisms and analysis their effect on the quantum states. Because of asymmetry in the real fibers, the two orthogonal polarization modes are propagated at different phase and group velocities. The difference in group velocities results in Polarization Mode Dispersion (PMD). It is created by random fluctuations of the residual birefringence in optical fibers, such that the State of Polarization (SOP) of an optical signal will turn randomly over time, in an unpredictable way. In optical quantum communication, quantum state measurement is necessary. The bottleneck for communication between far apart nodes is the increasing of the error probability with the length of the channel connecting the nodes. For an optical fiber, the value of absorption and depolarization of a photon (i.e., the qubit) increases exponentially with the length of the fiber.

MODELING OF FIBER-OPTIC COMMUNICATION CHANNEL FOR QUANTUM CRYPTOGRAPHIC SYSTEMS

Vladimir Alexandrovich Minaev, I. D. Korolev, Кулиш Ольга Александровна +1 more

The existing methods of information delivery to the strategic and tactical management of many government agencies are expensive, not always reliable and efficient. Therefore, quantum cryptographic systems (QCS) have been actively developed in recent years. However, there are problems with the use of the QCS associated with the reliability of information transfer. First, the existing fiber-optic communication channels (FOCC) are not designed to transmit single-photon signals, which leads to the complexity of their cryptographic protection. The second is insufficiently methodically developed calculation of energy losses and errors in the evaluation of the characteristics of information transfer in FOCC QCS. In article the analysis of the energy loss factors in the classical fiber-optic channel is carried out and the additive loss formula is discussed in detail. Then we consider the fiber-optic channel of quantum information transmission with the use of integrated optical devices. The additive formula of optical losses in such a channel is discussed. The features of losses in integrated optical devices are shown. The features of quantum cryptographic system of information transmission are considered. As a result, the model of FOCC QCS taking into account energy losses is presented, which allows competently in theoretical terms and visualize the passage of information through modern quantum cryptographically secure telecommunications while providing control in government structures.

The effects of different kinds of communication channels on the key indexes such as bit error rate and communication rate of quantum communication system, represented by quantum secure communication system, are systematically studied. For the actual channel, the transformation of quantum states caused by physical effects such as loss, dispersion and polarization mode dispersion in optical fiber channel is analyzed. With building in the spatial channel noise experimental data under different weather conditions, the mathematical model is established, and the software is designed and implemented.
