For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...

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 ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...
