A photon enters a cloud of atoms and emerges on the other side. When physicists calculate how long the atoms remained excited ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

A new set of upgrades to the International Space Station’s Cold Atom Laboratory is allowing NASA to probe quantum mechanics ...

UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop to chip-based systems, opening new possibilities for sensing, precision ...

Measuring the world precisely is much harder than it sounds. At very small scales, nature is noisy, and the rules of quantum physics make even the best instruments slightly uncertain. This limits how ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

Cold atoms are atoms that have been cooled to very low temperatures, below 1 mK, reducing their motion to a very low energy regime where quantum effects emerge. This makes them sensitive to some of ...

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small ...

Repeatedly energising a collection of ultracold atoms should destroy their collective structure, but quantum effects seem to counteract the process. “We expected to see the opposite,” says Nӓgerl. The ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...

(Santa Barbara, Calif.) — UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop to chip-based systems, opening new possibilities ...
