Development of a post-processing technique for a Quantum Key Distribution system.

Abstract

Quantum Information, Processing and Communication (QIPC) is a field concerned with technological implementations established on quantum mechanical phenomena. It is established on the concept that the action of manipulating information is controlled by the quantum physical effects. Therefore, quantum information can be characterised, quantified and processed as a physical body applying laws of quantum mechanics. QIPC consists of two major disciplines, quantum computing and quantum communication. Communication is bound by the transfer of information. Quantum communication applies some of the fundamental features of quantum mechanics, such as, the superposition principle and the Heisenberg uncertainty principle to protect the transfer of information. One of the most advanced quantum information related technology at present is Quantum Key Distribution (QKD). It is defined as a process of encoding information into a quantum carrier in the form of single photons and distribute that information amongst legitimate entities.
