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, ...

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

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 ...

For decades, time moved in one direction, now a growing number of quantum experiments are raising the unsettling possibility that the order of events may not be as fixed as humans once believed. For ...

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

Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. She reports on topics from maths and history to society and animals. Katie has a PhD in maths, ...

It looks like time travel, closed timelike curves, quantum mechanics, and quantum entanglement are once again at the centre ...

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 ...

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 ...
