Laboratory task - Polarization-based quantum key distribution
Poláková, Sylva ; Münster, Petr (referee) ; Klíčník, Ondřej (advisor)
This bachelor thesis focuses on a detailed analysis of quantum key distribution (QKD) with a focus on one-way prepare-and-measure protocols with discrete variable (DV-QKD) and polarization coding. The thesis is divided into a theoretical and practical part. The introductory theoretical part of the thesis provides a comprehensive overview of polarization as a fundamental physical phenomenon that is essential for understanding the operation of QKD protocols. Various aspects of polarization are discussed, including Jones vectors, Stokes parameters, and the Poincaré sphere. The next section covers the basics of quantum mechanics with a focus on qubit and the representation of quantum states. The work then moves on to quantum key distribution itself, where the basic principles of QKD are explained, and the most important protocols are also analysed. In the practical part, a laboratory task is designed to demonstrate the importance of polarization in the context of QKD protocols.
