Realising free-space communication with quantum cascade lasers

Abstract

I n today's fast-paced landscape of global communication, it is often critically important for many different groups to exchange messages securely, without any risk of eavesdroppers leaking the information they contain.So far, the most cutting-edge techniques for ensuring this level of security have often involved light waves transmitted through optical fibres, or radio waves sent through the air.However, these approaches face a number of drawbacks, particularly regarding the limited speeds at which large messages can be sent.Since the bandwidths available in optical fibres are strictly limited, they can quickly become saturated, leaving little room for information to propagate.

QUANTUM CRYPTOGRAPHY: PRINCIPLES, PROBLEMS, AND PROSPECTS

Ілля Геннадійович Калюжний

Quantum cryptography is a relatively new but promising method for secure data transmission. Today it is believed that it can ensure the absolute secrecy of data, resulting from the principles of quantum physics, on which it is based, namely the uncertainty principle of quantum Heisenberg. According to this principle cannot measure any aspect of photons without distorting thus irrevocably different option. That is the recipient of a message knows when attempting invasion in this necessarily knows.To create a quantum communication channel often use fiber optic lines or open space in which carriers serve single photons or pairs of entangled photons are often used.Three tasks facing cryptography are:1. Ensuring the confidentiality of messages sent via open communication channels.2. Authentication messages that confirm the validity of the information received and sent.3. Installing intrusion in fact, if it took place.Given the importance of information security, quantum cryptography technology will soon be available not only banks or large corporations but also individuals. Leading IT companies are in search of optimum circuit solutions that would produce industrial equipment for the transmission of confidential information available for mass use. The main obstacles for implementation of quantum cryptography methods are short distances, which can transmit information with modern facilities, high cost and cumbersome equipment. To solve these problems prompted the idea of creating a hybrid air-fiber system using satellite communications is proposed. The use of artificial satellites for the transmission of photons through the air opens the possibility of secret key clients in any part of the Earth and even beyond.It is also appropriate to review the possibility of using existing telecommunication and electrical networks for the transmission of quantum keys.

Design and construction of a high speed quantum key distribution device

Stuart Holt

Quantum cryptography has been proven to be the only practical method for fast distribution of secret keys needed for encryption. It enables absolutely secure information transfer from one party to another and allows for the detection of an eavesdropper without sacrificing security. This project involved designing and building a quantum cryptography device. This device has applications in many fields, including internet security as well as military communications. The data are encoded on single photons, which are sent through free space over a distance of about 30 cm. The electronics, which control the device however, are equally suitable for operation with fibre optic cables. The device was designed to operate in dark conditions within a laboratory. Currently, no research group has demonstrated transmission speeds faster than 8 kb/s. The aim of this project was to achieve bit rates faster than 10 kb/s, while operating under strict economic constraints. Although quantum cryptography was not demonstrated in the laboratory due to problems with the detector, the emission end, which generates single photons of light with one of two different polarisations, was shown to work as it was designed. The current design has limited commercial future due to the dark conditions under which the communication must take place. The project however has demonstrated that quantum cryptography is getting closer to becoming a reality.
