Abstract
Quantum computers have the potential to speed up certain problems that are hard for classical
computers. Hybrid systems, such as the nitrogen vacancy (NV) center in diamond, are among
the most promising systems to implement quantum computing, provided the control of the different
types of qubits can be efficiently implemented. In the case of the NV center, the anisotropic hyperfine
interaction allows one to control the nuclear spins indirectly, through gate operations targeting the
electron spin, combined with free precession. Here we demonstrate that this approach allows one to
implement a full quantum algorithm, using the example of Grover's quantum search in a single NV
center, whose electron is coupled to a carbon nuclear spin.
