Unveiling Quantum Secrets: Harnessing Undetected Light for Imaging and Insights into Photochemical Processes

Researchers have experimentally demonstrated a method called quantum imaging distillation with undetected light (QIUL) that can generate high-quality images of objects by removing noise. By using photon pairs and only detecting one photon while the other illuminates the object, the method is resilient to noise levels surpassing the actual signal of interest. The team implemented an interferometric modulation technique to distill the quantum image and verified its performance even under extreme noise intensities. This research contributes to the advancement of quantum imaging and its potential applications in fields like light detection and ranging (LIDAR).
