  • Abstract: A major challenge in the physical realization of quantum computing resides in characterizing a platform and developing the necessary techniques to produce any quantum algorithm or protocol with delity. Distinguishing itself among such platforms, the nitrogen vacancy center in diamonds is a substitutional point defect which occurs in the carbon lattice. The focus of this study is then to analyze the system as a two qubit quantum processor and the corresponding techniques required for the initialization, manipulation and reading of its quantum states. Firstly, we review the principles of quantum information processing with an ensemble of two energy level spins. The system's properties and a simpli ed model Hamiltonian are then analyzed, alongside its energy structure. Based on that, we discuss how the quantum states can be initialized and measured by a combination of optical and magnetic resonance techniques, while quantum gates can be achieved by the composition of microwave pulses. As an illustration of the studied concepts, we conclude by discussing the implementation of a non-thermalizing quantum thermometer protocol using the nitrogen vacancy system
