One of the major candidates for a potential room temperature quantum processor is the NV center in diamond. Due to the possibility to control and read out single electron and nuclear spins individually spectacular experiments like the creation of multipartite entanglement [1] have been demonstrated recently. Because of the extremely long coherence times the entanglement can be used to perform simple quantum algorithms. Using the nulcear spins of single 13C atoms and the electron spin of the NV-center itself as qubits we show first steps to perform algorithms similar to superdense coding and Deutsch-algorithm under ambient conditions.
