Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to ...

Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While already in use primarily in laboratory and research settings globally, ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...

A new method reveals hidden order in quantum systems, potentially transforming how they are measured and used.

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is.

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 ...

Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By ...
