Realization of a functional and reliable quantum-controlled device based surface plasmons polaritons (SPPs) depends on addressing and resolving a number of problems, such as plasmonic losses and the efficient coupling between nanoscale elements. One area that depends on a solution to these challenges is the coupling of single quantum emitters to plasmonic devices. Such systems can be used for the optical initialization and readout of the electronic spins, and can be leveraged for solid-state quantum communication and computing schemes, in addition to metrology, high-resolution magnetometry and sensing applications. In this context, the research presented in this thesis theoretically and experimentally investigates the perfonnance of nanoplasmonic waveguides under different fabrication and excitation conditions. Our work offers a promising route towards integrated quantum infonnation processing and nanoscale magnetometry systems based on nitrogen vacancy (NV) centres by demonstrating the viability and conservation of the NV centre spin systems after coupling to propagating SPPs.
