Fig. 1. Schematic of quantum heralding meta-holograms of eliminating noise.

Fig. 2. Design of metasurfaces and the classical holograms. (a) Unit phase and (b) transmission of H polarization for (c) metaholographic samples under an optical microscope; inset shows the unit cell, and scale bar is 500 nm. Black points in panels (a) and (b) are the final scales used in the metaholographic mapping. Metaholographic gray-scale image from (d) horizontal polarization and (e) vertical polarization by a gray-scale CCD camera.

Fig. 3. Experimental setup for obtaining heralded holograms on metasurface. (b) Intensity image of hologram obtained with single photons without heralding. (c) Hologram with heralding photons of vertical polarization. (d) Hologram with heralding photons of horizontal polarization. All images are obtained with 6000 100-ms-long 8-bit frames, and the background is subtracted.

Fig. 4. (a) Intensity hologram under an additional illumination as noise background. (b) Hologram with heralding photons of horizontal polarization in the same situation. (c) Metaholographic display influenced by multiple reflective lights. (d) Multiple reflective lights are suppressed significantly after quantum correlation imaging.
