A quantum network is the essential resource for distributed quantum computation and the enabling technology for secure quantum communication over large distances. Setting up such a network would require establishing quantum connections between local nodes which are capable of generating, processing and storing quantum information. Intensive research is carried out in laboratories around the world investigating suitable systems for implementing a quantum network. The experiments presented in this thesis explore the possible realisation with nitrogen vacancy (NV) centres in diamond. We study how these centres could serve as nodes in such a network and develop a toolbox that consists of quantum control and measurement acting on these nodes. Furthermore, we demonstrate how to connect nodes and create entanglement between two distant NV centres.
