The Nitrogen-Vacancy color center in diamond and its associated spin system is a promising candidate for the technical realization of a quantum computer and can be used as nanoscale electric and magnetic field sensor at room temperature. Manipulation and readout of the spin states is done by optical and microwave techniques. At high magnetic fields the spin system consisting of 14N and weakly coupled 13C nuclear spins can be used for improved readout and for information storage [1]. Further improvement can be achieved by error correction schemes. Here we experimentally demonstrate a code which corrects spin-flip errors of single nuclear spins.
