Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

And then it got me.” A handful of decades and an MIT physics doctorate later, Tan is the chief science officer (CSO) of ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...

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 ...

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 ...

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 ...

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

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 ...

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 ...
