MARGARIDA AMELIA FREITAS PEREIRA

Margarida Amelia Freitas Pereira is a Doctoral Research Personnel at the Research Center for Telecommunication Technologies within the University of Vigo, affiliated with the School of Telecommunications Engineering and Department of Signal Theory and Communications. She is part of the SC7 Antennas, Radar and Optical Communications research group.

• PhD in Telecommunications Engineering (2021), University of Vigo
• Research focus on quantum key distribution security
• Specializes in mitigating device imperfections in quantum communication

Her research focuses on Quantum Key Distribution (QKD) security analysis, particularly addressing source and detector imperfections, pulse correlations, and side-channel vulnerabilities. She develops security frameworks and finite-key analysis techniques while working on practical implementations that tolerate real-world hardware flaws. Her work combines theoretical security proofs with mathematical modeling for optical communication systems.

The article analysis reveals consistent focus on QKD security improvements, with particular emphasis on source imperfections, phase-error estimation, and loss-tolerant protocols. Her work spans from foundational research in quantum channel modeling (2019) to advanced security frameworks (2023-2025) addressing practical implementation challenges.

Margarida collaborates within the SC7 research group at the Research Center for Telecommunication Technologies, working on cutting-edge quantum communication projects. Her research directly addresses real-world implementation security for quantum cryptographic systems, focusing on practical deployment scenarios and device characterization.
