With its promise of secure communications, entanglement has been a highly demanded resource and is key to future quantum computation and communications. As protocols for such applications scale in size, so must the entangled states so that multiple parties get simultaneously connected to the quantum network. Luckily, short term solutions do not require new technologies, as it is possible to combine multiple bipartite sources to create multipartite resources. This thesis is a work presenting the basics of bipartite entanglement, especially the necessary building blocks required to make efficient, compatible, affordable and compact bipartite entanglement photon-pair sources, necessary for real-world applications. It also presents the basics of multipartite entanglement, from state generation to different properties and protocols making use of entanglement, and makes a proposal on how to combine all the previously described building blocks to make a robust multipartite entanglement photon source. The GHZ state created can be used for 3 or 4 qubits applications, ideal for small-scale networks, and can be scaled to a few more users at the cost of count rates. A short review of what is currently being done in the field follows this presentation, highlighting different milestones, such as the original proposals, current research pursued by different groups, and multiple current records achieved throughout the world. Lastly, a few applications related to quantum networks through quantum memories are presented due to their relevance in the field.
