Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations ...

Extremely cold atoms have been connected into a state of quantum “hyperentanglement” for the first time. This demonstrates a new level of control over their quantum properties, which could prove ...

For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms. Subscribe to our newsletter for the latest sci-tech news updates. In a ...

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 ...

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 ...

The research was published in the journal Science ("Observation of Shapiro steps in an ultracold atomic Josephson junction"). Two superconductors separated by a wafer-thin insulating layer – that's ...

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible ...
