- Abstract: Multiparticle entanglement is of great significance for quantum metrology and
quantum information processing. We here present an efficient scheme to generate
stable multiparticle entanglement in a solid state setup, where an array of
silicon-vacancy centers are embedded in a quasi-one-dimensional acoustic
diamond waveguide. In this scheme, the continuum of phonon modes induces a
controllable dissipative coupling among the SiV centers. We show that, by an
appropriate choice of the distance between the SiV centers, the dipole-dipole
interactions can be switched off due to destructive interferences, thus
realizing a Dicke superradiance model. This gives rise to an entangled steady
state of SiV centers with high fidelities. The protocol provides a feasible
setup for the generation of multiparticle entanglement in a solid state system.
