Application deadline: Thursday, April 30, 2026Research group: University of Sarajevo - Optical and Quantum Communications LaboratoryEmployer web page: https://euraxess.ec.europa.eu/jobs/414388Job type: PhDThe Faculty of Electrical Engineering at the University of Sarajevo (UNSA) invites applications for a fully funded PhD position within the Horizon Europe Marie Skłodowska-Curie Actions Doctoral Network (MSCA DN) QUESTING 101227218. The candidate will be part of the Marie Skłodowska-Curie Action project ‘QUESTING’, a groundbreaking Doctoral Network initiative aimed at revolutionizing the field of Quantum Technology by addressing critical gaps in interdisciplinary education and training. This program will cultivate a new generation of "Q-System Innovators," equipping doctoral candidates with expertise in quantum networks, hybrid classical-quantum systems, and interoperable cultural co-design. By integrating mathematics, physics, computing, and communications engineering with sociocultural and ethical perspectives, QUESTING pioneers an innovative approach to building scalable, robust, and adaptive quantum systems. The program's holistic methodology spans from theoretical advancements to real-world applications, including secure quantum communication, distributed resource management, and sustainable network topologies. Through its unique blend of participatory research, co-design processes, and industry-academic collaboration, QUESTING ensures alignment with global challenges, including cybersecurity, digital transformation, and equitable access to emerging technologies. This initiative is instrumental in advancing the European Union's Quantum Technologies Flagship and the UN Sustainable Development Goals, fostering innovation-driven growth while preparing Europe to lead responsibly in the quantum revolution. For this QUESTING PhD position at the University of Sarajevo, we are seeking a researcher to investigate the Design of QKD encryptors for emerging networking technologies. Objectives: (a) Exploring and defining the optimal network topology for satellite QKD networks: Node placement N, relay configurations R, and link efficiency will be analyzed to maximize coverage and minimize latency. Practical deployment scenarios will incorporate insights from APs such as Airbus, TIM, SURF, and LOGI. (b) Proposing a comprehensive QoS model: Metrics such as key generation rate, end-to-end latency, and packet loss rate will be quantified. Collaboration with APs will ensure the model aligns with real-world constraints. (c) Extending the QKD network simulation model: A novel QoS routing and signaling protocol will be incorporated, optimizing routing paths based on proposed QoS metrics. APs will be involved in iterative design discussions to evaluate implementation feasibility. (d) Validating and verifying results: Analytical frameworks, empirical data, and simulations will be used to evaluate performance. Engagement with APs will address deployment challenges and opportunities at continental, intercontinental, and global scales. The PhD student will spend 4 months at Trinity College Dublin (Ireland), hosted by Prof Dan Kilper and Prof Nicola Marchetti, to research network modeling and analytical verification of defined QoS models. The student will also spend 3 months at AIRBUS Defence and Space GmbH (Germany), hosted by Dr. Alberto Comin, to address resource constraints and performance limitations. Skills/Qualifications Applicants must hold Master's degree in Electronic / Electrical Engineering, Computer Science, Physics, Mathematics, or a related discipline with excellent academic performance.
