Free-range atoms, roaming around without restrictions, have been captured on camera for the first time – enabling physicists to take a closer look at long predicted quantum phenomena.

It’s a bit like snapping a shot of a rare bird in your back garden, after a long time of only ever hearing reports of them in the area, and seeing the food in your bird feeder diminish each day. Instead of birdwatching, though, we’re talking about quantum physics.

The US researchers behind the breakthrough carefully constructed an “atom-resolved microscopy” camera system that first puts atoms in a contained cloud, where they roam freely. Then, laser light freezes the atoms in position to record them.
