Abstract

This article presents the background, development, and implementation of a simulation framework used to model the quantum exchange aspects of Quantum Key Distribution (QKD) systems. The presentation of our simulation framework is novel from several perspectives, one of which is the lack of published information in this area. QKD is an innovative technology which exploits the laws of quantum mechanics to generate and distribute unconditionally secure cryptographic keys. While QKD offers the promise of unconditionally secure key distribution, real world systems are built from non-ideal components which necessitates the need to understand the impact these non-idealities have on system performance and security. To study these non-idealities we present the development of a quantum communications modeling and simulation capability. This required a suitable mathematical representation of quantum optical pulses and optical component transforms. Furthermore, we discuss how these models are implemented within our Discrete Event Simulation-based framework and show how it is used to study a variety of QKD implementations.
