A master’s thesis was discussed at the Institute of Laser for Postgraduate Studies\/University of Baghdad, presented by the student Omar Ali Mohammed, supervised by Lecturer Dr. Jawad Abdul-Kadhim Hassan, titled “Design and Optimization of Multi-Node Quantum Repeaters”.<\/span><\/h6>\n
The thesis addressed the design and comparison of multi-node quantum repeater systems with the aim of developing secure quantum communication networks for long-distance information transfer.<\/span><\/h6>\n
The study proposed several designs for serial quantum repeater networks connecting the Ministry of Higher Education and Scientific Research with the universities of Babylon, Sulimania, and Basra, based on real geographical data from the Iraqi Geological Survey. Mathematical models and computational simulations were developed using MATLAB to determine the optimal number of entanglement attempts that maximize the secure key rate in quantum communications.<\/span><\/h6>\n
The study also examined the impact of node location, quantum memory types, and network configurations on system performance. The results showed that each design has a unique signature in terms of the optimal number of entanglement attempts, and that using non-identical quantum memories with equal internal links and identical external links provides the highest performance efficiency.<\/span><\/h6>\n
The project also demonstrated that geographical obstacles significantly influence node placement, necessitating the use of flexible mathematical models to maximize the efficiency of these networks in secure long-distance quantum communication applications.<\/span><\/h6>\n
These results contribute to the development of an efficient and scalable infrastructure for quantum communications for future secure networks between administrative entities and research centers in Iraq.<\/span><\/h6>\n
The thesis was accepted as it met the requirements for the master’s degree.<\/span><\/h6>\n
