Quantum key distribution and other related protocols

Treballs Finals de Grau de Matemàtiques, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2024, Director: Luis Victor Dieulefait[en] The main goal of this work is to present an introduction to quantum computation and Quantum Key Distribution (QKD). The first chapter is dedicated to the basics of quantum mechanics needed to understand further concepts. Then the definition of quantum circuits is presented, along two examples: Quantum telepor- tation and the Deutsch-Josza problem.In the chapter about QKD, we will explain in detail the BB84 algorithm and some eavesdropping techniques, and we will take a look at the theory behind the EPR Protocol. Finally, we will explain the CHSH Game
