UR - https://www.unicat.be/uniCat?func=search&query=sysid:129679527 AB - This thesis by Alvaro Alarcón Cuevas explores advancements in quantum communication through the development of a fiber-optic platform. The work addresses the challenges of data security in optical networks by implementing quantum key distribution (QKD) methods, which utilize natural properties rather than mathematical constructs for data encryption. The thesis introduces a novel approach that combines phase-coded systems with time-bin schemes, effectively reducing losses and demonstrating compatibility with existing optical networks. The study successfully transmits phase-coded single-photon states over a 500-meter few-mode fiber and supports orbital angular momentum (OAM) modes, paving the way for more efficient quantum communication systems. This research is intended for professionals and academics in the fields of quantum mechanics and optical engineering. ER -
