The Relevance of Quantum Cryptography in Modern Cryptographic Systems

Sandstorm Enterprises, Inc.
Abstract
This paper explains the basic principles of quantum cryptography and how these principles apply to quantum key distribution. One specific quantum key distribution protocol called is described in detail and compared to traditional (nonquantum) cryptographic systems. It is explained how addresses some of the shortcomings of traditional cryptographic systems. The remaining technical limitations of are listed. A short overview of commercial implementations of quantum cryptography is given. The paper concludes with a brief discussion of the relevance and future viability of quantum cryptography in today's information security environment.
