This thesis is written in the context of quantum Internet development. We try here to contribute to the community by discussing some security concerns and by providing detailed models and simulation studies of quantum internet architectures and protocols. We explore different aspects of quantum networks on the path to the Quantum Internet. After introducing basic quantum information notions, we define the Quantum Internet and highlight the main goals and challenges. Then, we list a few bipartite and multipartite applications. After that, we study the composable security of a multipartite entanglement verification protocol, that is used as a building block by many other protocols. In the following chapter, we perform simulations of different quantum repeater protocols allowing connection between two distant nodes. These repeaters use a defect in the crystalline structure of the diamond, that we model. Finally, the last two chapters are dedicated to building and simulating an international quantum network architecture that minimizes the necessary hardware for the end users. We first study a metropolitan network, called the Quantum City, that we simulate in a Parisian context. We highlight the main parameters and today’s performances. Then, we study the feasibility of connecting different quantum cities separated by hundred of kilometers using satellites.
