Did scientists freeze light?
VERDICT
CONFIDENCE
100%
Direct Answer
Scientists have repeatedly demonstrated techniques to stop or 'freeze' light pulses using Bose-Einstein condensates, supersolid states, and crystal traps. Recent Italian research created a supersolid from photons in a semiconductor at near-absolute zero temperatures. Earlier experiments by Harvard's Lene Hau in 2000 and Princeton in 2014 also trapped light, confirming the phenomenon.
What the Evidence Shows
Multiple independent experiments validate light freezing: Harvard stopped light for milliseconds in sodium atom clouds, Princeton locked photons into solid-like states, and recent Italian work induced supersolid behavior in photons via photonic semiconductors. These rely on quantum effects at ultra-low temperatures, where photons interact strongly or form condensates. The claim holds as 'freezing' accurately describes halting light's propagation, though light resumes upon release.
Why People Get This Wrong
Some interpret 'freezing light' as violating physics laws or permanently stopping massless photons, but it involves temporarily storing light's information in quantum media without destroying photons. Media sensationalism amplifies this, yet peer-reviewed sources confirm controlled quantum manipulation.
What is a supersolid made from light?
A supersolid flows like a liquid while maintaining solid-like structure; Italian researchers created one from photons in a semiconductor near absolute zero, forming isoenergetic condensates with density modulation.[1][7]
How did Lene Hau stop light?
Lene Hau's Harvard team laser-cooled sodium atoms to near absolute zero, creating a Bose-Einstein condensate that halted light pulses for milliseconds by bogging them down in the atomic cloud.[3]
Can light be frozen for quantum computing?
Frozen light enables optical memory buffers and quantum information storage; Princeton's solid light and Australian crystal traps held pulses for seconds, promising faster, secure quantum computers.[2][5]
