Photons passing through an atomic cloud can appear to spend a negative amount of time inside it, emerging earlier than conventional intuition allows. Researchers used extremely weak measurements to show that the atoms themselves registered the same negative dwell time, while remaining consistent with standard quantum physics.

Photons passing through an atomic cloud can appear to spend a negative amount of time inside it, emerging earlier than conventional intuition allows. Researchers used extremely weak measurements to show that the atoms themselves registered the same negative dwell time, while remaining consistent with standard quantum physics.
The important change is experimental confirmation that negative dwell time is encoded in the atom-light
