Abstract
Secure communication needs are becoming increasingly critical for the Department of Defense (DoD) in the face of potential conflicts with near-peer adversaries. This thesis explores a novel approach to enhancing the security of space-based communication systems using the Hong-Ou-Mandel (HOM) dip phenomenon and white light interferometry (WLI). By leveraging quantum encryption principles, the research aims to develop a quantum authentication scheme capable of providing near-perfect security for optical communication systems. The experimental set up involved using a bi-photon source to demonstrate how to generate the “so called’’ HOM dip. A white light source was then used in the same configuration to demonstrate how white light interferometry can be used to stabilize the path length difference between the two arms of the interferometer to the precision needed to be able to observe the HOM dip over long distances.The study demonstrates the feasibility of generating the HOM dip with both fiber and free-space paths, establishing a foundational basis for a quantum authentication protocol. The results indicate that WLI can effectively calibrate the system to produce the HOM dip at desired wavelengths, ensuring robust authentication. This research proposes a theoretical satellite constellation utilizing the HOM dip for secure communication links.
