Modern Methods of Providing of Safety of Information by Quantum-mechanical Transformations

Abstract

This article is devoted to the review of basic perspective directions of development of quantum cryptography. Most perspective methods provided security of information by quantum-mechanic laws are examined in the article. Practical applicability of quantum cryptography is also examined for realization of the complete protected informative exchange at the physical level.
