A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

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 ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...
