Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

A team of physicists has created a cloud of ultracold atoms that stubbornly resists the most basic rule of everyday ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

More than 200 years ago, Count Rumford showed that heat isn’t a mysterious substance but something you can generate endlessly ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

"Quantum" may seem like a useless buzzword, but quantum computing is a real thing, and it's actually understandable even if ...

Physicists have struggled to understand the nature of time since the field began. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Time may not be ...

Rapid advances in the kind of problems that quantum computers can tackle suggest that they are closer than ever to becoming ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
