For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms. In a recent experiment, an alternating current was applied to a Josephson ...

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 ...

Quantum technologies are systems that leverage quantum mechanical effects to perform computations, share information or perform other functions. These systems rely on quantum states, which need to be ...
