  We propose a scheme enabling controlled quantum coherent interactions between
separated nitrogen-vacancy centers in diamond in the presence of strong
magnetic fluctuations. The proposed scheme couples nuclear qubits employing the
magnetic dipole-dipole interaction between the electron spins and, crucially,
benefits from the suppression of the effect of environmental magnetic field
fluctuations thanks to a strong microwave driving. This scheme provides a basic
building block for a full-scale quantum information processor or quantum
simulator based on solid-state technology.
