摘　　要：We propose a scheme to achieve nuclear–nuclear indirect interactions mediated by a mechanically driven nitrogen-vacancy(NV)center in a diamond.Here we demonstrate twoqubit entangling gates and quantum-state transfer between two carbon nuclei.When the dipole–dipole interaction strength is much larger than the driving field strength,the scheme is robust against decoherence caused by coupling between the NV center(nuclear spins)and the environment.Conveniently,precise control of dipole coupling is not required so this scheme is insensitive to fluctuating positions of the nuclear spins and the NV center.Our scheme provides a general blueprint for multi-nuclear-spin gates and for multi-party communication.
