In this article we investigate the dynamics of a single negatively charged nitrogen-vacancy center (NV^\ensuremath-) coupled to the spin of the nucleus of a 15-nitrogen atom and show that high-speed, high-fidelity gate operations are possible without the need for complicated composite pulse sequences. These operations include both the electron and nuclear spin rotations, as well as an entangling gate between them. These are the primitive gates one will need within a quantum node of a distributed communication network.
