Contemporary commercial quantum information security systems

Abstract

Quantum cryptography has attracted considerable interest among specialists in information security. The overwhelming majority of research projects in quantum cryptography are related to the development of quantum key distribution protocols. Absence of generalized classification & systematization makes it difficult to estimate the level of the latest achievements and does not allow using quantum technologies with full efficiency. From this viewpoint the analysis of existed quantum key distribution systems, strengths & weaknesses, its implementation prospects was carried out in the paper. It gives a possibility to formalize some actual problems of quantum key distribution systems and outline the ways of its solving.
