Paper Abstract

Quantum cryptography is a quickly developing field that brings direct applications of fundamentals of quantum theory. In this paper we present a brief review of the tasks and problems faced by classical cryptography and we point out the benefits of quantum cryptography to their solution. An overview of the experimental achievements and an outline of the principle of quantum key distribution are given. Various experimental approaches are compared. The quantum cryptographic device built by the authors is described and its use for mutual identification system is presented.
