Solid state systems such as NV centers play an important role in quantum information processing and the fundamental investigation of quantum physics. In this project, we propose to investigate strong couplings between single NV centers and surface phonon polaritons in a piezomagnetic superlattice. With this strong magnetic coupling, we investigate new schemes for hybrid quantum devices that may be useful in quantum information. At the single quantum level, we study the quantum phenomena and underlying physics between single NV spins and surface phonon polaritons. We also propose to make use of the spin and optical properties of the NV centers, and the excellent features of surface phonon polaritons in a piezomagnetic superlattice, which can help to realize the strong coupling limit. This work allows for the construction of hybrid quantum devices with NV spins and piezomagnetic metamaterials, which can provide a promising platform for implementing quantum information.
