CMOS Camera Detects Entangled Photons in Image Plane
Analysis
Key Takeaways
- •Demonstrates detection of spatially entangled photon pairs using a standard CMOS camera.
- •Operates at mesoscopic intensity levels, significantly higher photon flux than photon-counting methods.
- •Achieves image- and pupil plane correlation measurements.
- •Employs a tailored correlation analysis to suppress detector artifacts and intensity fluctuations.
- •Extends quantum imaging techniques beyond the photon-counting regime.
“From the measured image- and pupil plane correlations, we observe position and momentum correlations consistent with an EPR-type entanglement witness.”
