Abstract

Integrating quantum information protocols with metasurfaces opens new opportunities for nonlocal and high-capacity optical information processing. Here, we experimentally demonstrate remote multichannel vectorial meta-holography enabled by polarization entanglement between spatially separated photon pairs. By combining a compact, phase-robust Sagnac entanglement source with a full-Jones-matrix dielectric metasurface, we encode multiple elementary holographic contents and conditionally retrieve their individual and composite outputs through joint input-output polarization projections. The selected holographic content is identified through polarization-resolved coincidence measurements, whereas local single-channel detection alone does not provide access to the corresponding conditional channel information. Compared with single-channel detection, the coincidence reconstruction achieves a signal-to-noise ratio enhancement of 4.74 dB. This work establishes a compact quantum-correlated metasurface platform for multichannel holographic information processing, with potential applications in correlation-gated imaging, encrypted communication, and nonclassical optical information processing.
