Description
Summary:Quantum cryptography is the result of a synthesis of ideas from fundamental quantum physics and classical encryption that may radically change the way in which the confidentiality of information and the integrity of communications networks are protected. In this paper we discuss the issues that influence the design of practical quantum cryptography schemes for optical fibre-based communication systems.
