Quantum technologies have evolved in the last few years to the point where experiments that were once thought theoretical have become experimentally feasible. In this context, we have developed a quantum network simulator based on NetSquid, in which we have incorporated different network protocols and applications. This simulator supports arbitrary topologies and entanglement based QKD protocols. Additionally, traffic models and routing are implemented, through an abstract Network Manager. These experiments aim to recognize the experimental limitations that could emerge in a functional quantum network, emphasising in the use of state of the art quantum technology models, which will be parametrized by any of the properties that define the components of a quantum network: quantum channel distances, damping and dephasing proper times in memories, fidelity of quantum sources, photon fiber coupling, etc. We propose a thorough study to find, of all the aforementioned properties, which of them are the limiting factor in network applications. To characterize these boundaries, two types of applications have been considered of interest:
