Diamond spins are an ideal test bed for exploring quantum physics of few well controllable qubit systems. Defect center electron spins show strong coupling to a light field and at the same time interact with few surrounding nuclei in the lattice. As a result the system usually constitutes a few qubit system with excellent coherence and controllability even at room temperature. It fulfills all characteristics of a quantum register including single shot read-out capability. The talk will highlight how to use such systems for carrying out quantum algorithms which might be even usable for sensing applications.
