Abstract

This thesis addresses two challenges involved in the culmination of the Quantum En- crYption and Science Satellite mission. This mission aims to demonstrate quantum key distribution (QKD) in space. The first part of the thesis will be dedicated to the intro- duction of a quantum random number generator. This generator will be based off of the arrival time of photons and subsequently used to produce random bits that will be turned into the random states necessary for the QKD protocol. The latter half of the thesis will address creating the random states for the protocol. This is non-trivial due to the finite resources involved in the physical apparatus that comprises the chosen weak coherent pulse source for the QEYSSat mission.
