The purpose of my thesis is to describe the concept of the quantum repeater, further demonstrating its operation process and the associated challenges with a simulation.
With the growing number of quantum devices and protocolls, comes the need for better and better quantum communication systems. For such systems today, the distance between the endpoints still poses a huge limiting factor. One possible solution for this can be the use of quantum repeaters.
Considering the novelty of the investigated area, I start my thesis with a brief historical overview , followed by a short introduction to the theoretical basics. I continue with describing the concept of entanglement swapping and exploring the possibility of a quantum repeater. After that i examine some of the most recent experimental realizations of the protocoll. Later I present the outline of my simulation. The thesis finishes with revisiting the challenges and problems related to the protocoll by reviewing the simulation results of a generalized model of the quantum repeater.
