The preparation and manipulation of single-photon and multiphoton quantum states play critical roles in the development and application of the quantum information technology. Based on miniaturization and integration of quantum devices, the effective preparation and manipulation of quantum states are an emerging problem in the quantum information technology field. Metasurfaces, as planar artificial nanostructure arrays, can effectively control the amplitude, phase, and polarization of a light field in sub-wavelength scale, which provide a good methodology for the design of micro-nano optical devices. Recent advances have demonstrated that high-efficiency metasurfaces are a powerful platform for the realization of integrated and miniaturized quantum devices. This paper reviews the design principles and broad applications of high-efficiency metasurfaces in the visible and near-infrared regimes. In addition, this paper discusses recent key metasurface approaches to improve the performance of single-photon emitters and preparation and manipulation of multiphoton entangled states.
