  We propose a scheme of quantum information processing with NV-centers
embedded inside diamond nanostructure. Single NV-center placed in the cavity
plays role of an electron spin qubit which evolution is controlled by microwave
pulses. Besides, it couples to the cavity field via optical photon exchange. In
their turn, neighbor cavities are coupled to each other through the photon
hopping to form a bus waveguide mode. This waveguide mode overlaps with all
NV-centers. Entanglement between distant centers is organized by appropriate
tuning of their optical frequency relative to the waveguide frequency via
electrostatic control without lasers. We describe the controlled-Z operation
that is by one order of magnitude faster than in off-resonant laser-assisted
schemes proposed earlier. Spectral characteristics of the one-dimensional chain
of microdisks are calculated by means of numerical modeling, using the approach
analogous to the tight-binding approximation in the solid-state physics. The
data obtained allow to optimize the geometry of the microdisk array for the
effective implementation of quantum operations.
