CMOS Camera Detects Entangled Photons in Image Plane

Published:Dec 31, 2025 14:15
1 min read
ArXiv

Analysis

This paper presents a significant advancement in quantum imaging by demonstrating the detection of spatially entangled photon pairs using a standard CMOS camera operating at mesoscopic intensity levels. This overcomes the limitations of previous photon-counting methods, which require extremely low dark rates and operate in the photon-sparse regime. The ability to use standard imaging hardware and work at higher photon fluxes makes quantum imaging more accessible and efficient.
