Query: Nuclear-nuclear interaction mediated by a mechanically controlled
  nitrogen-vacancy-center spin in diamond   We propose a scheme to achieve nuclear-nuclear indirect interactions mediated
by a mechanically driven nitrogen-vacancy (NV) center in diamond. Here we
demonstrate two-qubit entangling gates and quantum-state transfer between two
carbon nuclei in diamond. In such a system, the NV center interacts with a
nearby nuclear spin via a dipole-dipole interaction. Under the quantum Zeno
condition, 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 in a polygon geometry with each vertex occupied by a nuclear
spin.
