Privacy is paramount when communicating sensitive information in today's increasingly networked world. Both the business and government sectors have ever-more demanding secure communication needs. Conventional information assurance methods face increasing technological challenges and future threats, including unanticipated advances in mathematics, high-performance computing, and the possibility of large-scale quantum computation. Quantum cryptography is an emerging technology in the field of cryptographic systems where quantum mechanics is used to guarantee secure communication between two parties. This paper discusses the limitations of conventional cryptography and some recent advancement in Quantum Cryptography.
