An adjustable dimmer turns a basic on/off detector into a tool for recognizing the quantum nature of light.

A regular light detector used to only say 'particles here' or 'not'. Scientists found a loophole: if you put an adjustable dimming shutter in front of the detector, the pattern of yes/no answers changes and reveals whether the light is 'quantum' or 'normal'. A simple idea that unlocks the secrets of the micro-world.

🎯 At maximum dimming, quantum light seems unwilling to vanish: the detector keeps stubbornly clicking away, revealing the source's mysterious nature.
