A group of scientists from ITMO University in Saint Petersburg, Russia has developed a novel approach to the construction of quantum communication systems for secure data exchange. The experimental device based on the results of the research is capable of transmitting single-photon quantum signals across distances of 250 kilometers or more, which is on par with other cutting edge analogues. The research paper was published in the Optics Expressjournal.
Information security is becoming more and more of a critical issue not only for large companies, banks and defense enterprises, but even for small businesses and individual users. However, the data encryption algorithms we currently use for protecting our data are imperfect – in the long-term, their logic can be cracked. Regardless of how complex and intricate the algorithm is, getting round it is just the matter of time.
Contrary to algorithm-based encryption, systems that protect information by making use of the fundamental laws of quantum physics, can make data transmission completely immune to hacker attacks in the future. Information in a quantum channel is carried by single photons that change irreversibly once an eavesdropper attempts to intercept them. Therefore, the legitimate users will instantly know about any kind of intervention.
Heriot-Watt University is a public university based in Edinburgh, established in 1821 as the world’s first mechanics’ institute. It has been a university by Royal Charter since 1966. It has branch campuses in the Scottish Borders, Orkney, Dubai, and Putrajaya in Malaysia.
Heriot-Watt is divided into seven schools and one institute that coordinate its teaching and research:
- The School of the Built Environment, incorporating architectural engineering, civil engineering, structural engineering, construction management, surveying and urban studies;
- The School of Engineering and Physical Sciences, incorporating chemical engineering, chemistry, electrical, electronic and computing engineering, mechanical engineering and physics;
- The School of Life Sciences, incorporating applied psychology and biology;
- The School of Management and Languages, incorporating accountancy and finance, business management, economics and languages;
- The School of Mathematical and Computer Sciences, incorporating actuarial mathematics and statistics, computer science and mathematics;
- The School of Textiles and Design;
- Edinburgh Business School, which offers postgraduate courses at MBA, MSc and DBA level; and
- The Institute of Petroleum Engineering, incorporating petroleum engineering and renewable energy technology.
