A University of Toronto experiment demonstrating that photons can spend a negative amount of time within an atom cloud has successfully passed peer review and been published in Physical Review Letters. This groundbreaking quantum effect, which makes photons appear to exit a cloud before entering, was confirmed after averaging approximately one million test runs. Researchers emphasize that this phenomenon does not imply time travel and is fully explained by existing physics, with no faster-than-light signaling involved. AI
IMPACT Confirms unexpected quantum properties; no immediate practical applications foreseen, but photonic systems are key to quantum computing.
