Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

One of the pieces of equipment for the quantum random number generator in the NIST Boulder laboratories. Very little in this life is truly random. A coin flip is influenced by the flipper’s force, its ...

Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world.

In the 1960s, a group of physicists and historians began a massive project meant to catalogue and record the history of quantum physics. It was called Sources for History of Quantum Physics (SHQP). As ...

Physicists have identified a new superfluid phase in a class of quantum systems that, until recently, looked too unstable and ...

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 TU Wien have developed a one-dimensional “quantum wire” using a gas of ultracold atoms. In this system, both ...

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 ...
