It originated from a combination of quantum mechanics and information technology. The present paper presents the possibilities of using quantum mechanics in cryptography and considers whether there are any practical solutions to the important class of problems regarding the security of transmitted information. %K Quantum mechanics %K quantum information %K quantum cryptography %K security %K credibility %U http://versita.metapress.com/content/c74p62240313l8x6/?p=267303c7301e43fa9abd4b439c492009&pi=4
