Descripció:
Quantum Key Distribution (QKD) is a key enabling technology for secure communications, offering information-theoretic security based on the principles of quantum mechanics. Among the different QKD implementations, optical communication systems—both free-space and fiber-based—play a central role in current and future quantum communication infrastructures.
This project focuses on the development of a comprehensive link budget model for an optical QKD communication system. The work will address the characterization of the main physical and system-level parameters that affect the performance of QKD links, including optical losses, atmospheric or channel effects, system efficiencies, and noise sources. The model will be designed to be flexible and scalable, allowing its application to different operational scenarios and system configurations. The project will emphasize analytical modelling and simulation, providing a solid framework for performance assessment and preliminary system design.
Objectius:
The main objective of this project is to develop a robust and adaptable link budget model that supports the analysis and evaluation of optical QKD communication systems. The results are intended to support design trade-offs and future system optimization activities.
Tasques a realitzar / Característiques:
The project will begin with a review of the fundamentals of optical QKD systems and link budget analysis methodologies. This will be followed by the identification and definition of relevant system parameters, including transmitter, channel, and receiver characteristics. Based on this, an analytical link budget model will be developed and implemented, potentially supported by numerical simulations. The work will include the evaluation of different operational scenarios and a discussion of model limitations and possible extensions. Documentation and clear presentation of assumptions and results will be an integral part of the project.
